Incompatibility with shapely 1.7.0.

As reported by Eric Reed, AROSICS is incompatible with shapely versions greater than 1.6.4:

I'm just getting started with AROSICS -- this is great. Great paper and documentation. I'm filing a bug report here instead of gitlab since I'm not sure how with that enterprise instance.

The latest version of shapely (v1.7.0) is incompatible with arosics (at least when running with the CLI in global mode). I needed to downgrade to an earlier version (conda install -c conda-forge shapely=1.6.4 did the trick). Consequently running through the install commands at http://danschef.gitext.gfz-potsdam.de/arosics/doc/_sources/installation.rst.txt (without pinning the shapely version) will error out.

EDIT: The following exception is raised:
