1190e53e9b avif: always indicate endless loop 
avif does not support loops but endless loop was the behavior before
460085 was fixed, so a workaround is added.

350ce1b990 avif: return false in canRead() when imageIndex >= imageCount 
Otherwise when `cache: false` is set in AnimatedImage, QMovie will try
to read the image forever.

9ab64dbf22 heif: use heif_init/heif_deinit with libheif 1.13.0+ 
In recent libheif, application should use
heif_init/heif_deinit calls. Unfortunately, these calls are
not thread-safe in released 1.13.0 version yet (will be in the
future) and HEIFHandler is often created in different threads.
So we have to guard their use with a mutex.

65a20b43fc Camera RAW images plugin 
Plugin to read RAW camera images based on LibRAW.

- Supersedes MR !86 
- Support to LibRaw 0.20 and 0.21-Beta
- Support to multi-shot images: use imageCount(), jumpToImage() to select the wanted shot
- By default generates 16-bits sRGB images using camera white balance and interpolation AHD
- Should fix CCBUG: 454208: on my Debian with KF5.96 and the pulgin installed, I see the preview of all my RAW files (ARW included) in Dolphin

News compared to V1 (MR !86)

- Fix possible stack overflow due to the huge size of LibRaw class
- Fix image allocation with Qt 6 (make use of QImageIOHandler::allocateImage()) 
- Support to XMP metapacket
- Support to quality option. For e.g. you can focus on quality (q = 10) or speed (q = 1)
- oss-fuzz available [here](https://github.com/mircomir/oss-fuzz/tree/raw_fuzz/projects/kimageformats)

feb6d9b20f Fix image allocation with Qt 6 
To make the plugins fail to allocate if the image size is greater than QImageReader::allocationLimit() it is necessary to allocate the image with QImageIOHandler::allocateImage().

Note that not all plugins have been changed and some others are not tested in the CI (maybe due to missing libraries).

PS: the following message is printed by QImageIOHandler::allocateImage() if the size is exceeded: "qt.gui.imageio: QImageIOHandler: Rejecting image as it exceeds the current allocation limit of XXX megabytes"

5e59d950bd jxl: support both old 0.6.1 and new 0.7.0 libjxl API 
New libjxl API changed the way how lossless 16bit depth images
must be encoded: codestream level 10 must be set,
which implies use of container format.
Unfortunately, there isn’t version number inside libjxl header yet,
so we must detect new version on cmake/PkgConfig level.
