Reactivate basemap dependency

[DominicDirkx]

Due to a build error here (only on Mac and Linux):
https://dev.azure.com/tudat-team/feedstock-builds/_build/results?buildId=938&view=logs&j=5c51a9b2-339f-5e52-ee1c-93d36cabd2b6&t=86db673d-28f1-5516-b5f3-125685f56516

we've deactivated the basemap dependentcu in tudatpy.plotting

12675be

This should be resolved in the future.

The error output in the Azure build is the following:

However, the libtiff library is present in the conda environment, making the above error strange
