Format codebase

[Kartstig]

Background

The re-formatting of the codebase should be done in a single commit so that anyone developing can re-base and continue their work without much interruption

Approach

• Use the ruff linter to format the code
  Some benefits to ruff is that it's particularly fast
• Use black

Notes

See @Kartstig 's fork code for an example of how to implement a check in CI
