Add Tooling for flake8 and black

[SmithChart]

This PR adds support for running flake8 and black both locally and in Github Actions.

Locally we can simply run make qa and both tools will run.

On Github both tools run in Actions:

• flake8-messages are used to annotate the code pushed
• The black action will only indicate if it would re-format any code.

This PR re-formats the code using black and fixes problems reported by flake8.
