Fix build with older openEXR versions

Dynamic exception specification is not allowed in c++-17. The enforcement needs
to be relaxed for the kimg_exr plugin when using openEXR versions older than 2.3.0.

-and subsequent owner(s) (each and all, an "owner") of an original work of
-authorship and/or a database (each, a "Work").
-
-Certain owners wish to permanently relinquish those rights to a Work for

-## Plugin status
-
-The current implementation of a plugin may not be complete or may have limitations
-of various kinds. Typically the limitations are on maximum size and color depth.
-
-The various plugins are also limited by the formats natively supported by Qt. 
-For example, native support for CMYK images is only available since Qt 6.8.
-
-### HDR images
-
-HDR images are supported via floating point image formats from EXR, HDR, JXL,
-JXR, PFM and PSD plugins.
-It is important to note that in the past these plugins stripped away HDR 
-information, returning SDR images.
-
-HDR images return R, G and B values ​​outside the range 0.0 - 1.0.
-While Qt painters handles HDR data correctly, some older programs may display 
-strange artifacts if they do not use a tone mapping operator (or at least a 
-clamp). This is not a plugin issue.
-
-### Metadata
-
-Metadata support is implemented in all formats that support it. In particular,
-in addition to the classic `"Description"`, `"Author"`, `"Copyright"`, etc... where 
-possible, XMP data is supported via the `"XML:com.adobe.xmp"` key.
-
-Please note that only the most common metadata is supported.
-
-### ICC profile support
-
-ICC support is fully implemented in all formats that support it. When saving, 
-some formats convert the image using color profiles according to
-specifications. In particular, HDR formats almost always convert to linear
-RGB.
-
-### Maximum image size
-
-Where possible, plugins support large images. By convention, many of the
-large image plugins are limited to a maximum of 300,000 x 300,000 pixels.
-Anyway, all plugins are also limited by the 
-`QImageIOReader::allocationLimit()`. Below are the maximum sizes for each
-plugin ('n/a' means no limit, i.e. the limit depends on the format encoding).
-
-- ANI: n/a
-- AVIF: 32,768 x 32,768 pixels, in any case no larger than 256 megapixels
-- EXR: 300,000 x 300,000 pixels
-- HDR: n/a (large image)
-- HEIF: n/a
-- JXL: 262,144 x 262,144 pixels, in any case no larger than 256 megapixels
-- JXR: n/a, in any case no larger than 4 GB
-- PCX: 65,535 x 65,535 pixels
-- PFM: n/a (large image)
-- PIC: 65,535 x 65,535 pixels
-- PSD: 300,000 x 300,000 pixels
-- PXR: 65,535 x 65,535 pixels
-- QOI: 300,000 x 300,000 pixels
-- RAS: n/a (large image)
-- RAW: n/a (depends on the RAW format loaded)
-- RGB: 65,535 x 65,535 pixels
-- SCT: 300,000 x 300,000 pixels
-- TGA: 65,535 x 65,535 pixels
-- XCF: 300,000 x 300,000 pixels
-
-### Sequential and random access devices
-
-All plugins work fine on random access devices while only some work on
-sequential access devices.
-Some plugins, such as PSD, allow reading RGB images on sequential access 
-devices, but cannot do the same for Lab files.
-
-**Important: some plugins use `QIODevice` transactions and/or 
-`QIODevice::ungetChar()`. Therefore, the device used to read the image must not
-have any active transactions.**
-
-### Memory usage
-
-Qt has added many image formats over time. In older plugins, to support new
-formats, `QImage` conversion functions have been used, causing memory
-consumption proportional to the size of the image to be saved.
-Normally this is not a source of problems because the affected plugins
-are limited to maximum images of 2GiB or less.
-
-On plugins for formats that support large images, progressive conversion has
-been used or the maximum size of the image that can be saved has been limited.
-
-### Non-RGB formats
-
-PSD plugin loads CMYK, Lab and Multichannel images and converts them to RGB 
-without using the ICC profile.
-
-JXR, PSD and SCT plugins natively support 4-channel CMYK images when compiled 
-with Qt 6.8+.
-
-### The HEIF plugin
-
-**This plugin is disabled by default. It can be enabled with the 
-`KIMAGEFORMATS_HEIF` build option in the cmake file.**
-
-### The EXR plugin
-
-The following defines can be defined in cmake to modify the behavior of the plugin:
-- `EXR_CONVERT_TO_SRGB`: the linear data is converted to sRGB on read to accommodate programs that do not support color profiles.
-- `EXR_DISABLE_XMP_ATTRIBUTE`: disables the stores XMP values in a non-standard attribute named "xmp". Note that Gimp reads the "xmp" attribute and Darktable writes it as well.
-
-### The HDR plugin
-
-The following defines can be defined in cmake to modify the behavior of the plugin:
-- `HDR_HALF_QUALITY`: on read, a 16-bit float image is returned instead of a 32-bit float one.
-
-### The JXL plugin
-
-**The current version of the plugin limits the image size to 256 megapixels
-according to feature level 5 of the JXL stream encoding.**
-
-The following defines can be defined in cmake to modify the behavior of the plugin:
-- `JXL_HDR_PRESERVATION_DISABLED`: disable floating point images (both read and write) by converting them to UINT16 images. Any HDR data is lost. Note that FP images are always disabled when compiling with libJXL less than v0.9.
-- `JXL_DECODE_BOXES_DISABLED`: disable reading of metadata (e.g. XMP).
-
-### The JXR plugin
-
-**This plugin is disabled by default. It can be enabled with the 
-`KIMAGEFORMATS_JXR` build option in the cmake file.**
-
-The following defines can be defined in cmake to modify the behavior of the plugin:
-- `JXR_DENY_FLOAT_IMAGE`: disables the use of float images and consequently any HDR data will be lost.
-- `JXR_DISABLE_DEPTH_CONVERSION`: remove the neeeds of additional memory by disabling the conversion between different color depths (e.g. RGBA64bpp to RGBA32bpp) at the cost of reduced compatibility.
-- `JXR_DISABLE_BGRA_HACK`: Windows displays and opens JXR files correctly out of the box. Unfortunately it doesn't seem to open (P)RGBA @32bpp files as it only wants (P)BGRA32bpp files (a format not supported by Qt). Only for this format an hack is activated to guarantee total compatibility of the plugin with Windows.
-- `JXR_ENABLE_ADVANCED_METADATA`: enable metadata support (e.g. XMP). Some distributions use an incomplete JXR library that does not allow reading metadata, causing compilation errors.
-
-### The PSD plugin
-
-PSD support has the following limitations:
-- Only images saved by Photoshop using compatibility mode enabled (Photoshop default) can be decoded.
-- Multichannel images are treated as CMY/CMYK and are only loaded if they have 3 or more channels.
-- Duotone images are treated as grayscale images.
-- Extra channels other than alpha are discarded.
-
-The following defines can be defined in cmake to modify the behavior of the plugin:
-- `PSD_FAST_LAB_CONVERSION`: the LAB image is converted to linear sRGB instead of sRGB which significantly increases performance.
-- `PSD_NATIVE_CMYK_SUPPORT_DISABLED`: disable native support for CMYK images when compiled with Qt 6.8+
-
-### The RAW plugin
-
-Loading RAW images always requires a conversion. To allow the user to
-choose how to convert the image, it was chosen to use the quality parameter
-to act on the converter. The quality parameter can be used with values ​​from 
-0 to 100 (0 = fast, 100 = maximum quality) or by setting flags to 
-selectively change the conversion (see also [raw_p.h](./src/imageformats/raw_p.h)).
-
-The default setting tries to balance quality and conversion speed.
-
-### The XCF plugin
-
-XCF support has the following limitations:
-- XCF format up to [version 12](https://testing.developer.gimp.org/core/standards/xcf/#version-history) (no support for GIMP 3).
-- The returned image is always 8-bit.
-- Cannot read zlib compressed files.
-- The rendered image may be slightly different (colors/transparencies) than in GIMP.
