Have some rough edges still but largely successful in converting entire sites

Have this running on several websites, with legacy ones regenerating all images successfully. It’s the cleanest approach I’ve seen to maintaining an all AVIF (or WebP) image site.

Two issues that I think have easy fixes:

1. It allowed the ‘Force Regenerate Thumbnails’ plugin to convert existing WebP images to AVIF, none of which came out okay and needed manual replacement. Perhaps that was the regenerate plugin being too heavy handed, but it still shouldn’t happen.
2. Adding the ability to exempt certain images or fields from conversion would be ideal. For instance, as several major social media platforms still don’t support AVIF, it would be great to be able to exempt Yoast Social Open Graph images or Feature Images (the default OG image).
