These methods are allowed to return `None` when the implementation (or
PEP 302 loader [18]_ in effect) for whatever reason cannot calculate

extend this API, to include a new method `.get_paths()` which will
return a 2-tuple containing the path to the source file and the path
to where the matching `pyc` file is (or would be).
