The benefit, of course, is speed.
"foo" > "bar" is around 25% faster
with the new library.
is 120% faster. But the real speed benefits probably come when a program
is able to input filepaths as ByteStrings, manipulate them, and operate
on the files, all without using String.
It's extensively tested, not only does it run all the same doctests that the filepath library does, but each function is quickchecked to behave the same as the equivilant function from filepath.
While I implemented almost everything, I did leave
off some functions that operate on PATH, which seem unlikely to be useful,
and the complicated
normalise and stuff that uses it.
