[Feature Request] Add zstandard support #3725
Description
If you recompress the GBA library from zip to zst(level 19 compression) it goes from 13.5GB to 12.5GB, using zeekstd to compress it into a seekable archive you can mount it with ratarmount without extracting the archive to play the compressed rom. But it would be cool to skip all of that and just be able to load the zstd compressed rom like a zipped up rom.
