Add linters for the project

[sloboegen]

What do you think about adding several popular linters/formatters for this project, i.e. isort, black, flake8 (or ruff)?

Also, do you want to migrate to poetry from pipenv/tox/...?

@sloboegen 👍

i'd like to use black b/c i think it encompasses what flake + pylint were doing before.

for dependency management, i'd really like to use pdm: https://github.com/pdm-project/pdm

But, I'm also okay with using poetry if you think that's an easier approach.

Thanks for opening up this issue.
