get rid of cartopy being an optional dependency and remove basemap functions

[Swanson-Hysell]

It seems like it would be easier to maintain the code if we got rid of all the legacy Basemap functions and made it so that Cartopy is a required dependency. There can be some versioning issues with Cartopy and its dependencies like Shapely, but overall we make heavy use of it and not being able to have it as a required package results in us having to do if statements and use the has_cartopy variable.

Do you have thoughts on this @ltauxe?

i agree. let’s do that. also, i struggle with some of the mapping functions which should take an ax object and add to that instead of using a figure number. lisa
