Support pathlib Path()

[natter1]

I would like to use pathlib Path objects whenever possible, as it prevents lots of issues likly to happen with simple strings. Any chance to allow the use of Path-objects in pyansys?

I'd like to! Wonder how best to incorporate with the string commands for APDL?

[natter1]

I guess we will still need (ideally only a single) method to convert and check paths for APDL (because of some edge cases that might not work with APDL).

Maybe commands should accept both, str and Path-objects?

Still, by accepting, using and returning Path-Objects at least most of the issues on the python-side should be catched. And there have been a lot of them already.
