Add pre-commit configuration and autoformat

[abhidg]

This PR adds pre-commit configuration. I have opted to use ruff as the linter, open to alternatives. Reason for choosing ruff over flake8, black is that it is one tool that combines most Python autoformatting and linting functions in one and is very fast.

• Add pre-commit configuration, fixes Configure pre-commit config #66
• Initial pre-commit run with ruff autoformatting
• Add git blame ignore revisions file

Good choice with Ruff, and it kinda fits with the ethos of the project
