JPEG XL (.jxl) image format

[olavrb 1]

For future proofing, it would be great if Emby added general support for JPEG XL (.jxl). It could be used for multiple things, like:

• Storing and viewing photos
• Media metadata (album art)
  • Recompress existing JPEG and PNG losslessly to shave down the metadata database

Decode support is probably dependent on support in browsers and OS-es? Apple will have JPEG XL in their next major OS version. More about adoption:

HI, yes I agree we should support this. Currently we use a combination of Skia and libvips for image processing, so the holdup on this would be related to them first adding support for it, e.g.: https://github.com/libvips/libvips/discussions/2055
