Hello, Is there a way in the API to take a single input .heif file with multiple AVIF frames and output one .heif-file per frame without re-compressing each frame ?

Currently the pixbuf loader only supports loading files - it would be great if it also supported saving files, which would enable applications like Pinta (https://github.com/PintaProject/Pinta/issues/653) to support editing `.heic`...
