By default, MyPy will ignore modules without __init__.py's

[Farmer-Pete]

As I'm sure you are aware, in Python3, __init__.py is no longer required for modules.

The only problem is that in MyPy, when the __init__.py file is missing, it won't find the module and since ignore_missing_imports is set the True, the result is that large portions of the code will be ignored.

The fix for this is to set namespace_packages to True
