Updated use of shapely.geometry.Polygon and shapely.geometry.collection.GeometryCollection

[Adaickalavan]

1. Newly released shapely==2.0.0 includes type check which fails when Polygon is instantiated using sequence of Point objects.

   # File: shapely/geometry/polygon.py
   if not np.issubdtype(shell.dtype, np.number):
       # conversion of coords to 2D array failed, this might be due
       # to inconsistent coordinate dimensionality
       raise ValueError("Inconsistent coordinate dimensionality")

   • Hence, Polygon is instantiated using sequence of coordinate pairs instead of sequence of Point objects.

2. Newly released shapely==2.0.0 deprecates iteration over multi-part geometries.

   • Hence, geoms property is used to access the constituent parts of a multi-part GeometryCollection object.

Does this generalise to previous versions?

This works in previous version shapely==1.8.1.
