Would you consider adding the new AVIF image format?

[slightfoot]

AVIF is a new image format derived from the keyframes of AV1 video. It's a royalty-free format, and it's already supported in Chrome 85 on desktop. Android support will be added soon, Firefox is working on an implementation, and although it took Safari 10 years to add WebP support, I don't think we'll see the same delay here, as Apple are a member of the group that created AV1.

If this is not something your looking into, would you be interested in receiving a PR for such an addition.

I won't have time to look into this in the near future, butI'd be more than happy for a PR if someone else wants to implement it. Sounds like a cool format.
