Conversion to package

[johnyaku]

This is a very cool tool, and it solves an important problem for us.

I'd recommend it to all of my teammates if only it were a little easier to install -- ideally via pip or conda (or both).

Here is a guide for converting a python project into a package: https://towardsdatascience.com/how-to-convert-your-python-project-into-a-package-installable-through-pip-a2b36e8ace10

Then there are the official docs: https://packaging.python.org/en/latest/tutorials/packaging-projects/

I'd do this myself and open a PR except that I won't have the bandwidth for the next few weeks.

Also, there is a typo in the list of depenencies: psutils shoul be psutil. Fixing that would be a good start!
