Shapely runtime warnings in newer climada_env builds

[sarah-hlsn]

Newer versions of the climada_env build (not sure exactly when this issue started) are getting many shapely runtime warnings when doing any kind of plotting (mostly of the kind: invalid value in buffer/intersection). This issue seems to come from somewhere outside climada, but it does not seem to be in relationship to the version of shapely installed.

It's possibly related to the OS though - haven't encountered it neither on Linux nor Windows.
(Please report if you prove me wrong)

I also get flooded with shapely warnings due to calls to the buffer function somewhere in Hazard.plot_intensity, but I could not track the source so far.
