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.
Instead of resizing the bytearray to the potential size and then reading
into it, ask the device to read into a bytearray, this way instead of a
crash because we're trying to resize to a too big number we get a nice
maxSize argument exceeds QByteArray size limit

- Fix parasite "gimp-comment" not set due to null QImage
- Support to parasite "icc-profile" using Qt 5.14+ API
- Added parasite "gimp-image-metadata" as QImage metadata "XML:org.gimp.xml"
- Added a XCF with XML metadata and icc prifile embedded in autotest folder (generated by GIMP 2.10.30)
- Tested with Qt 5.15.2 and Qt 6.2.3 under Windows and Qt 6.2.3 under macOS
In Qt5 converting a QByteArray to a QString stops at the first null byte,
in Qt6 the QByteArray size is respected, and trailing null bytes are
therefore included in the final QString. Explicitly determine the length
of the string data to deal with that.
Enable decoder to use more threads.
8bit YUV->RGB conversion is significantly faster
when AVIF_RGB_FORMAT_RGBA format is used,
because libavif can use libyuv to perform conversion quickly.
Prefer faster AVIF_CHROMA_UPSAMPLING_FASTEST when decoding animation.
Encoder speed changed from to 8 to 7.
Recent AV1 encoders got faster,
so it is OK to switch to better compression quality.
Remove obsolete image/avif-sequence mime-type
as it was merged with image/avif.
The moc process already rebuilds the plugin when the JSON file changes, consequently the additional parameter is not needed.

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.
New libavif 0.9.1 apply some very strict standard compliance
checks by default. Unfortunately, it rejects many files made by
libheif-based apps (GIMP, ImageMagick) in the past.
libheif 1.12.0 (released on May 5, 2021) addressed the problem,
but it would be good to extend grace period, allowing other
projects and distributions to upgrade to fixed version.
Allow saving Qt-unsupported variants of ICC profiles, they could be
correctly handled by apps with wider color management support.
Change way how QColorSpace is created to avoid
rare problems in some apps.
