rust-filepatterns: use bytes instead of String
In my initial patch, I introduced an unnecessary hard constraint on UTF-8
filenames and patterns which I forgot to remove. Although the performance
penalty for using String might be negligible, we don't want to break
compatibility with non-UTF-8 encodings for no reason.
Moreover, this change allows for a cleaner Rust core API.
This patch introduces a new utils module that is used with this fix.
Finally, PatternError was not put inside the Python module generated by
Rust, which would have raised a NameError.
