@avaldebe has shown us the many benefits of using ruff as a linter / formatter. We should move to use ruff instead of black and isort.

Describe the solution you would like to see
A clear and concise description of what you want to happen.

• A PR applying ruff to the pyaerocom code base.
• Changes in the dependencies to drop isort and black and add ruff.
• Changes in the pre-commit hooks to just use ruff.
• The commit of the major changes to the code should be added to the .gitignore

Additional context
This should happen rather soon after any large outstanding PRs are merged. #962 should be merged into main-dev before a PR for this is drafted.
