Allows backends (like ext2, apfs, btrfs, xfs etc.) to communicate with the frontends (currently including only FUSE and Redox), by implementing the Filesystem and FilesystemMut traits.

• ext2/ext3/ext4: Read-only (+writing metadata, but I haven't checked if this actually works in a while). Ext2 filesystems can be read in quite an error-free way, whereas ext4 should be mostly working.
• apfs: Read-only (everything isn't implemented to fully cover the limited spec provided by Apple, however reading files and listing directories is implemented)
• btrfs: WIP (reading B-trees is implemented, and probably error-free)
• xfs: TODO
• f2fs: TODO

• FUSE: Read-only access to files and directories, including metadata.
• Redox: Same as FUSE.
• Linux kernel modules: TODO
• macOS kexts: TODO

• Create/use a proper parsing library. scroll is currently used in fal-backend-ext4, but some structs need manual parsing.
• Optimizations
• Testing, which requires either storing binary fs images in the repo, or depending on the system's mkfs. There is a limited test suite, but it has to be expanded and improved.
