Need testers for Python 3 version

[dlenski]

It's 2020, and Python 2.7 is at EOL.

Please test the python3 branch and give feedback on anything that doesn't work properly. (So far, so good for me 🤞)

Starting from 136bacb, I changed the shebang to python3. So far, so good --- I will let you know if I notice any issues!

[cxw42]

No problems! I see you merged the python3 branch --- can this issue be closed?

I was just about to open an issue to drop support for PY2 😄. I been using it exclusively on PY3 on Windows through git-bash with no issues for almost a year now.

If you make the minimum 3.5, you can use pathlib module to cleanup some of the file operations. Currently 3.6 is the lowest supported Python version.

That's a good idea. Want to write a PR to do this? 😬

opened a PR for it. I didn't use it to the full extent it could have used since I'm still tracing how some of the code is interacting IRT to the in/out objects.
