Add an AVIF muxer by re-using the existing the mov/mp4 muxer.
AVIF Specifiation: https://aomediacodec.github.io/av1-avif
Sample usage for still image:
ffmpeg -i image.png -c:v libaom-av1 -avif-image 1 image.avif

ffmpeg -i video.mp4 animated.avif

I arbitrarily decided to use the syntax 'opt=@filename' to match e.g.
