feat(refactor): Ruff linter

[psyray]

Is there an existing feature or issue for this?

• I have searched the existing issues

Expected feature

Submitted by @jxdv

Currently the styling of the python codebase is inconsistent. Some examples:

• Mixing up naming conventions (some functions use snake case / camel case etc.)
• Some files follow the PEP8 spacing between functions / classes / constants etc. and some don't.

Proposed solution:
Writing a GitHub action for Ruff linter. Of course this would take quite a while to refactor the whole codebase, but I can see the project benefitting from it.
