Models API (demo)

[wpbonelli]

Demo programmatic access to example data/models via https://github.com/fatiando/pooch.

This could be convenient for

• feature: self-contained notebooks, API for example models modflowpy/flopy#1872 (comment)
• Self-contained example notebooks modflow6#1348
• autotests in flopy, modflow6 and elsewhere

A simple proof of concept is available here: https://github.com/wpbonelli/modflow-devtools/tree/models-api

If this seems worthwhile, flopy may be a better place for it because the API

• could return MFSimulation or model directly
• could construct models lazily from Python/flopy on first call then cache input files, as an alternative to downloading them from GitHub
