feat: black formatter

[joao-conde]

@joamag main differences are:

• trailing commas in sequences
• no space between the equals (=) in kwargs key and value

Example black config properties: https://github.com/psf/black/blob/main/pyproject.toml

An interesting read: https://luminousmen.com/post/my-unpopular-opinion-about-black-code-formatter

Maybe black is too opinionated for us and not configurable enough?
