Damien George fb77be1506 py: Include filename in errors from loading/saving files via "open".
This improves error messages in mpy-cross:
- When loading a .py file that doesn't exist (or can't be opened) it now
  includes the filename in the OSError.
- When saving a .mpy file that can't be opened it now raises an exception
  (prior, it would silently fail), and includes the filename in the
  OSError.
