Thorough scouring of docs + doc build infrastructure

[jGaboardi]

This PR:

• swaps out conda for micromamba for up to 3x faster environment solves
• adds dedicated general and spatial package version printing
• adds linting as a pre-req for testing to run
• Resolves love and care for docstrings, etc. #141

[jGaboardi]

This PR morphed into some monster doc work (see #141). Going to keep this PR going as a DOC [WIP] and open a new, smaller one specifically for the original intent: CI updates (now being handled in #144).

Major points

  • standardize docstring formatting
  • add math & code formatting where appropriate
• tutorials
  • review all tutorials and reformat where appropriate
  • clean up cells, code, and viz
  • review all text for grammar, spelling, punctuation, clarity etc.
• doc site and doc build infrastructure
  • update conf.py and build_docs workflow
  • update Makefile to copy over tutorials form ./notebooks to ./docs/notebooks before rendering
  • add binder links to tutorials
  • rebuilt doc site locally to ensure everything renders properly

@sjsrey Got time for a not-so-quick review....? 😨

[sjsrey]

Huge amount of work here. Awesome.

Should be nbsphinx, no?

[jGaboardi]

Absolutely yes. Good catch.
