Ruff for linting and formatting

[bluginbuhl]

Currently, the generated cookie-cutter project uses black, ruff.isort, and flake8. These tools are configured in different locations (pyproject.toml and setup.cfg). These configurations could all be consolidated to use ruff. Additionally the base repo could also use ruff for formatting and linting, which would simplify the dev-requirements.

Two levels of decisions here:

• Do we add support for ruff? (I think yes)
• Do we make ruff the default for everything (formatting + linting)? (I also think yes)

In this world, there would be two or three options:

1. ruff for everything (default)
2. black + flake8 + isort
3. nothing?

Support for ruff was added #387 - it's now the default linting & formatting option. It will be a part of the 2.1.0 release.

If you don't want to wait, you can use the most recent version of the template by pulling from the master branch, ccds -c master
