Add python development dependencies

[GreasySlug]

Currently, there are no specified packages or libraries for Python development

I added pyproject.toml as the beginning of it for now, as it will be needed in the future

black is a de fact standard of python code formatting

The following may also be added

• flake8 ruff
• typing
• mypy
• pytest

Do mtshiba think these need to be added for dev dep?

Changes proposed in this PR:

• add requirements.txt pyproject.toml
• formatting with black

Personally I prefer to manage dependencies with pyproject.toml rather than requirements.txt.

And I think it's good to add the dev dependencies you listed above.

Sorry, I don't know much about pyproject.toml besides poerty
