Move to new WMM module?

[dlakaplan]

Hi. I am currently trying to use RMextract for some simple calculations, but my installation is very slow because of the need to compile the WMM module. I see that there is a new simplified WMM python module:
https://github.com/space-physics/wmm2020
I don't know if it's equivalent, but it seems to have built and installed much more quickly on my system. This may be difficulties with an M1 Mac, but if there were a way to move to this WMM module instead, it might speed things up for others as well.
