Setup build infrastructure (dependency management, pyproject.toml, ...)

[michaelfruth]

Setup build infrastructure:

• Use pipenv for development (see https://github.com/streamlit/streamlit/tree/develop/lib as reference)
• Use MakeFile to format, sort, lint, etc..
• Create pyproject.toml

Hi @michaelfruth

Are you still planning on getting back to this issue?

[michaelfruth]

Yes, I still plan to do it, but I don't have any capacity for this at the moment.

stale, re-opened to be grabbed by anyone (including @michaelfruth, if you find the time :-))
