.avif support

I would love to see .avif support, hope you can squeeze it in by using an existing library. Avif is mainstream in all browsers nowadays, and suitable to use as default long-term storage instead of .jpg . Thanks!

I also use .avif since about a year or more now. It is very efficient. All my old .jpg fotos are now in .avif. The reduced file size is great; image quality is acceptable even at low percentages (though I try to not go below 30% for important fotos; even at 50% though avif beats jpg soooo easily).

It would be really useful if eom works fine via .avif. Perhaps there is even wrapper library that could be re-used since I reckon avif should become even more popular over time.

I'm not sure there's anything needed from EOM to support it 100%: it uses the gdk-pixbuf library that is based on loaders for each formats, and there is one in libavif's contib directroy, so installing this should make it Just Work™.
In Debian (and probably Ubuntu), just install libavif-gdk-pixbuf and it works.
