EXIF support for JXL (JPEG XL) files is missing

[insectinegate]

IrfanView doesn't show EXIF information embedded in JXL files. This is quite unfortunate.

The info is there but it's encoded using the brotli compression algorithm.

Please add!

JPEG XL isn't finalized, it's still under development. Therefore it's likely it isn't feature complete right now. Please be patient until then.
