This PR changes a few things:

• Switch from pylint to ruff for better lint coverage and faster lint times
• Add pyright for static type checking
• Lint with black for consistent styling
• Introduce isort for import sorting
• Add pre-commit hooks for ruff, black and isort
• Introduce tox for testing and linting
• Use tox in CI pipelines
• Fix issues found by Pyright, Ruff etc.
