📚[DOC]: Use consistent doc strings format across the repo

[ktangsali]

How would you describe the priority of this documentation request

Critical (currently preventing usage)

Is this for new documentation, or an update to existing docs?

New

Describe the incorrect/future/missing documentation

We should use consistent, numpy-style for the docstrings. Presently, there is some code which uses the google style.

Do you have a pre-commit hook in mind to enforce this? I think this is an excellent idea.
