Switch to Namespace Packaging

[simurgh9]

I discovered that the latest and cleaner way to import code in Python is not by using __init__.py files as it traditionally had been.

The contrast is explained in an answer to the Stack Overflow question,

What is __init__.py for?

Read the links,

• https://docs.python.org/3/reference/import.html#namespace-packages
• https://peps.python.org/pep-0420/

And, switch over or explore switching over to the cleaner method.
