JPEG XL support!

[Flavored-37860]

JPEG XL is a next-generation royalty-free image codec with superior compression, providing about ~60% size savings when compared to original JPEG at the same perceptual quality, while supporting modern features like HDR, animation, alpha channel, lossless JPEG recompression, lossless and progressive modes.
In a nutshell it's the most efficient image compression format there is.

This seems interesting, although it's a bit early to adopt it in Caesium. I'll have a look anyway of course, as it may improve the JPEG compression.
