idea: MapBox

[jonjab]

Do we want to add using a MapTiles / MapBox / AGO background in our lesson somewhere?

Does that exist in the canonical? If it doesn't, maybe it should.

I reviewed the canonical and there is no use of basemaps. I think it's a good idea, and if included, it should be at the end of episode 8. The last challenge of ep 8 is "plot raster and vector data together", so I think it adds up nicely here that it's also possible to use a basemap you get from some library/package instead of a raster you have on your laptop.
