Model attributes

A wflow model in HydroMT also has a set of specific attributes, on top of the ones from the model API. These are:

flwdir	Returns the pyflwdir.FlwdirRaster object parsed from the wflow ldd.
basins	Returns a basin(s) geometry as a geopandas.GeoDataFrame.
rivers	Returns a river geometry as a geopandas.GeoDataFrame.
