[Feature Request] Add MAME's CHD #240

7z/zip/liz/lz4/lz5/zst are streamable but not random-accessable so they're not practical for game data storage because in order to use them you need to completely decompress them first. Unlike CHD it's random-accessable, perfect for game data storage and can be use on the fly. CHD is lossless and it uses LZMA/FLAC for its compression method.
