mpy-cross/mpy_cross: Add Python wrapper for mpy-cross.
Rather than invoking mpy-cross directly via system/subprocess in our build tools and other tools, this provides a Python interface for it. Based on https://gitlab.com/alelec/mpy_cross (with the intention of eventually replacing that as the "official" pypi distribution once setup.py etc are added).
