[jeffersonkr]

issue #32

• added black, ruff config
  • (100 characteres per line was set as default)
• added pre-commit config
• run black and ruff on all project files

We're missing the pre-commit in test-requirements.

Ps.: Soon, I'll migrate the project to poetry, but for now, let's use what we have.

Hey @jeffersonkr sorry about answering in a different era. Do you still want to finish it? If so, take a look at the recent changes that I did and I'd recommend using ruff and black instead of flake and isort. Lemme know.

[jeffersonkr]
