What does this implement/fix? Explain your changes.

C# naming conventions are different from python naming conventions. CamelCase is the usual convention for properties and methods in C#, while snake_case is preferred in python (pep8).

When using ansys-pythonnet to bind C# to python, python users will use the C# APIs with the C# conventions. This breaks expectations for python users.

This PR adds an option to enable pep8 aliases for python bindings, allowing python code to use pep8 even if the C# code does not.
