A "universal" format validator whose goal is to validate every byte of as many of the most common file formats as possible (I'm up to about 190, to varying degrees of coverage; turns out many formats don't have checksums, and some formats' parsing won't break on corrupt data)

Written in Zig, it has a C FFI and a CLI for mac/windows/linux.

The purpose of this is to feed into a different project I'm working on that is for-pay.
