[QGIS-Developer] Is there a recommended way to include external Python packages

[C Hamilton]

Generally speaking it is not recommended, but I have done it with several
of my plugins (KML Tools, Date/Time Tools). If your python package is OS
dependent (not pure python) then you don't want to include it with your
plugin. My Density Analysis plugin can use the optional H3 library (which I
think might be worthwhile for QGIS to include as a part of its libraries),
but it is machine dependent so I did not include it. It is not ideal to
have users pip install the library, but you have to weigh the costs vs. the
benefits of using some library.

Good luck!
