191e5e6a69 EXIF improvements and bugfixes
- Fixes a writing issue for float values ​​less than 1
- Fixes a missing definition of `EXIF_DATETIMEDIGITIZED` tag
- Adds support for some common camera shot metadata
- Adds missing metadata to writing tests

The following plugins automatically gain support for the new metadata: AVIF, IFF, HEIF, JXL, JXR, PSD and TGA (V2E).

The new metadata added with this patch is usually saved by smartphones (e.g. iPhone or Google Pixel).

9c6c0c01ae TGA: Support for TGA specification 2.0
Adds TGA 2.0 compliance:
- Support for Extension Area, Developer Area and Footer (metadata support)
- Support for 15-bit and 16-bit per pixel images (both RGB and Indexed)
- Full support for rotation on reading (we cannot use Qt transformations because only a subset is part of the TGA specification)
- When writing you can choose the supported version (subType)
- Improved writing speed (approximately 10 times) and removed whole image conversions (significant memory savings)

It pass the [TrueVision TGA 2.0 conformance suite](https://github.com/zigimg/test-suite/tree/master/fixtures/tga).

Test changes:
- Read test: added ability to skip a specific test on sequential devices (via JSON behavior file)
- Write test: added the ability to set the subType when writing (via JSON properties file)

Closes #37

- Image transformation support via EXIF data

[RGBN/RGB8](https://wiki.amigaos.net/wiki/RGBN_and_RGB8_IFF_Image_Data) files are used in Impulse's Turbo Silver and Imagine.

e5cf9caac5 JXR: added support to EXIF metadata
Improved metadata support via EXIF ​​metadata. Since JXR is based on a TIFF container, EXIF ​​data is read directly from the file so it always works (even with versions of libjxr that don't have the metadata reading API).

It also solves the following issues:
- Incorrect date format on saved JXR files (was saved in ISO format instead of `yyyy:MM:dd HH:mm:ss`).
- Incorrect date type setting in EXIF ​​data: the `DateTime` tag should be updated on every save (verified by GIMP and Photoshop). Our `CreationDate` metadata is the equivalent of the EXIF ​​`DateTimeOriginal` tag.

Closes #22

ae00c110f2 JXL: Resolution and metadata support via EXIF
- Added a class to read and write minimal exif metadata.
- JXL plugin uses EXIF metadata to load/save the resolution of the image (like GIMP).
- JXL plugin uses EXIF metadata to set/store text metadata and date/time.
- Enable info display in Dolphin (JXL File -> Properties -> Details on a JXL file, see image below).
- Enabled read test to check also image metadata and resolution.

- Metadata are not set (as with resolution)

4dedd88c08 SCT: added read only support
I keep adding old formats to ensure interoperability with as many programs as possible...

This plugin adds read-only support for the Scitex SCT format only. This format is also supported by Photoshop in read and write (SCT test cases were created by Photoshop).

b5d5abe0ea JXL improvements
Highlights of the patch:
- Supersede MR !249
- Added FP16 and FP32 images support thus preserving HDR values (read / write, required libjxl 0.9+).
- Added Gray8 and Gray16 support (read / write).
- Indexed images are saved as Gray8 when palette is gray scale.
- Binary images are saved as Gray8 (does JXL natively support binary images?).
- Simplified writing process by partially removing the use of additional buffers.
- Added XMP metadata support by decoding/encoding Boxes.
- Changed maximum image size in pixels in accordance with JXL feature level 5 (still limited to 256 megapixels).

Compatibility: 
- Older versions of this plugin load FP images correctly as UINT16 (obviously losing HDR info).
- HDR images saved with this patch are also loaded correctly by Gimp and Photoshop.
- Grayscale images saved with this patch are also loaded correctly by Gimp and Photoshop.

Compilation modifiers for cmake file:
- `JXL_HDR_PRESERVATION_DISABLED`: disable the FP support (behaves like previous versions).
- `JXL_DECODE_BOXES_DISABLED`: disable metadata reading (behaves like previous versions).

ac1006cc66 JXR: Fixed image reading on sequential devices
The following changes are done:
- Fixed an error when copying image from sequential device
- Return error when the image exceed 4GB size on writing*
- Enabled JXR tests

(*) Note that when writing an image larger than 4GiB, the JXRLib does not give any error but the resulting saved image id wrong.

63e21ee5f3 Disable JXR plugin due to crashes in JXRLIB
I ran a simple fuzzer on all the plugins in the repo and the JXR one crashes every few seconds. I attach some files (I have many more) that cause the crashes. For the moment I think it's best to keep it deactivated.

The strange thing is that for the same plugin I had created the PR on oss-fuzz which ran locally for over an hour without problems. I'm a bit confused.

7899c27a80 exr: write support and more
- Added support for writing EXR files
- Large image support (tested with 32GiB 16-bit image)
- OpenEXR multithreaded read/write support through the use of line blocks
- Build option to enable conversion to sRGB when read (disabled by default)
- Multi-view image reading support
- Options support: Size, ImageFormat, Quality, CompressRatio
- Metadata write/read support via EXR attributes

The plugin is now quite complete. It should also work on KF5 (not tested): if there is the will to include this MR also on KF5, let me know and I will do all the necessary tests.
