Pathlib port (Windows/Linux/MacOS)

[vChavezB]

Based on the comments from @noahp I have rebased my last pull request to veriify that unit tests pass for different versions with github actions and python module tox.

Changes

Fixed

• Unit tests due to parsing of basefile name as a pathlib type. Changed to string representation.
• Path for elf file was not working in windows. Parsing elf_file_path as pathlib to have a generic path representation to fix this.

I did a local pull request on my fork and it fails for windows with python 3.6,3.7 and 3.9

I will have a look on this...

Ok I think the pipeline should now pass :)

You can ignore that codecov check error by the way! I'll take a look at this patch soon. Looks solid though if it's passing all the tests on our 18 (!) supported configurations, amazing work!
