Python type stub files 📜

[joamag]

Description

With Python 3.6+, there's been primitive support for type hinting.
We want to be able to offer this richer type of support through the usage of type hinting.

Implementation

Make use of type stubs to add types to the major entry point functions/methods.

There's already some work done d0cc0f4.

@hugo-gomes interesting, let's run that over part of the codebase and check the quality of the results - it could be a very good starting point
