* WIP: preparation for JPEG XL support
* jxl: add loading support
* update jxl abstract
* add support for saving jxl (lossless not working)
* everything works except setting lossless explicitly
* remove unused header
* fix wrong quality logic
* remove debugging statements
* fix lossless encoding
* improve support for grayscale images
* use JXL instead of JPEGXL everywhere
* oops do not make libjxl a requirement
* update years
* silence some warnings
* simplify loader fast path logic
* allow python to save jxl and webp
* update error message with supported formats
* Allow setting image quality in Python
The setting is ignored where it does not make sense.
* round quality in JPEG saver
* improve error message in CMake
* add jxl support to imglab
* add Davis's suggestion

* make sure grayscale is 8 bit
* update abstract: JPEG XL can store grayscale images
* add more methods to query basic info from JXL
* documentation formatting
* Apply Davis' suggestions

* Return shortcut in disturb_colors
No need to do anything if both gamma and color magnitudes are set to 0.
* Fix typo
This happens for being lazy and making the change directly from GitHub...
This allows us to greatly simplify the self supervised learning example:
- the computation in user code was a bit too distracting
- avoids duplicated computation/allocation of this matrix
- avoids edge case where net outputs are zero due to trainer synchronization
* save_png() works with buffers and streams
* optimization for bgr_pixel
* explicit overloads for matrix<> and matrix_exp<>. Added docs for new savers
* refactored loading implementations details. In my view, easier to read, mirrors saving implementations details, and supports iostreams. We could make the callback API public, and we could support a ton of APIs...
* test for iostreams
* oops
* - reduced code size by templating byte type
- docs
* spelling
* i hope i haven't made a pig's breakfast out of this

When I created the issue template, I was expecting that we would get fewer people opening bugs when they can't build dlib, so I added the bug label to all submitted bugs.
However, that is not the case, and we still get bug reports which are not really bugs, and this label prevents the @dlib-issue-bot from closing them if there's no activity.
I think the bug label should only be added manually after verifying that the bug report is actually a bug.
* Fix convolution backward filter cache when using cudnn
* Apply suggestions from code review
