sids_from_shapely() for convex is broken

sids_from_geoseries(df, resolution=7, convex=True)

results in

obviously traces back to

starepandas.sids_from_shapely(geom=geom, resolution=5, convex=True, force_ccw=True)

[NiklasPhabian]

which obviously traces back to

starepandas.sids_from_polygon(polygon=geom, resolution=5, convex=True, force_ccw=True)

[NiklasPhabian]

certainly an issue with pystare's cover_from_hull()

Maybe broken for some geometries. But not generally broken.

I can easily do:

sdf = geopandas.read_file('../tests/data/hms_smoke20210209.zip')
sdf = starepandas.STAREDataFrame(sdf)
sids = sdf.make_sids(level=10, convex=True)
