chore: move bitfield library to lib director
...
I'd presonally prefer to use a git submodule here but It doesn't quite
seem like git submodules are possible for individual files. I'll have to
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!
