Pre-commit tools

[benoit9126]

A lot of small modifications here:

• I have added pre-commit with a set of basic tools.
• I applied this to the entire repository, so a lot of files have been modified.
• The configuration for this set of new tool is in a pyproject.toml file and in a .flake8 file (as flake8 does not support pyproject.toml)
• I have added a GHA related to pre-commit
• I forced the usage of f-strings
• Shapely raised some warnings that I tried to remove

Coverage decreased (-0.3%) to 76.754% when pulling f0fa6ed on benoit9126:pre-commit into 12f93f1 on tilezen:master.

just want to make sure that the removal of the setup.cfg doesn't have any side effects for existing users.

[rmarianski]

does this have any consequences for existing usage?

I have moved this parameter in the pyproject.toml file. I wanted to limit the number of configuration files. I did it in advance as I hope that, in a future PR, the setup.py file will be removed from the repository (to be replaced with additional data pyproject.toml)
