Rekai Nyangadzayi Musuka 80d49e03d6 chore: move bitfield library to lib director 
I'd presonally prefer to use a git submodule here but It doesn't quite

check with FlorenceOS every once and a while to ensure that there are no
lingering soundness issues with the library.

Thanks to @N00byEdge for this wonderful library!
