Here is what I did:

* Applied Black.
* Added pyproject.toml with configuration for Black.
* Modified Flake8 rules.
* Added a Black GitHub workflow.

The application of Black can use some touches here and there. You need to
use the same Black version. You may want to modify some lines before and
after (I did just things I caught for one reason or another - you cannot
review all changes). You may run Flake8 to check for long lines after you
applied Black and see if there is something you can resolve. I did separate
PRs for different directories, but that was because the codebases are
different in each and also a little bit to minimize conflicts with other
PRs (these should not be an issue with grass-addons repo). Commit per
directory, but then squashing them when merging the PR might be a good
approach for grass-addons.
