Example B19730_04_14-shapely.py broken

[RyanBurnside]

Hello, when running the example B19730_04_14-shapely.py there is an error that lib.to_wkt()
can only be called with ndarray object.

I first cat the file's contents so you can see it's not tampered with.

I managed to regress shapley back to 2.0.3 which seems to have resolved this.

Possible solution: Do a listing on your Book's environment to suggest the proper book versions of assorted libraries in both pip and conda. Then for the next version of the book update them to modern stable variants.
