Gensim functions should accept pathlib.Path objects

[DavidNemeskey]

I got this error after 2 days of training:

pathlib has been an integral part of the Python standard library since version 3.4 (more than 10 years ago), and it makes working with file paths much easier. Please add support for it in the library.

@DavidNemeskey , can i work on this one ?

[DavidNemeskey]

@123Soham-bhatia Of course, I would be happy to see this being worked on. I am not a Gensim developer, however, so I won't be able to guide you / merge the PR.

[123Soham-bhatia]

@DavidNemeskey no issues, i can work on this alone and make it work , you can assign it to me .

@123Soham-bhatia As I said, I am not a Gensim developer, so I don't have write access to this repo.
