Install pre-commit for repository

- Ensure we are formatting properly and consistently
  - Users can in principle choose to opt out of automatic hooks by not
    installing the tool in the repo
- Simplicity of incluing linting into CI
  - For stability we run them initially in parallel to existing linting
    scripts
- Scalability and futher development is simple as we can use existing
  solutions instead of implementing our own linting setup
