Cleanup and docs

[eddiebergman]

• Remove unused files
• Put some spacing for bash commands
• Enable some new doc functionality through plugins
  • Colored blocks
  • Code output
  • Nice little blocks to breakup walls of text
• Remove setup.py and requirements.txt (everything specified in pyproject.toml)
  • less files
  • Tools like poetry and pypi can read the statically define pyproject.toml file which is not possible with a setup.py which is a dynamic python file (makes the repo play very nice with those tools)
