Use Protocols instead of ABCs

### 📝 Description of the feature

I recently learned about Protocols in Python, which is a more Python-esque way to create interfaces. The changes are very minor and should not impact any code using this library. I suggest we make the same change to these interfaces.

More details on Protocol at: https://peps.python.org/pep-0544/

Example of a different API that was recently [changed from an ABC to a Protocol](https://github.com/ansys-internal/bdm-python-api/pull/54).
