Problem loading branches

[Ni3lz87]

I got the following error while trying to load branches from the example data::

This probably has to do with an inconsistency between shapely and geopandas. Did you use geopandas 0.8.2 and shapely 1.8.0? If not update (or downdate) to that combination. Note that delft3dfmpy is deprecated; you can now use dhydamo in hydrolib 0.2.0.
