Update pypi project page

[mandjevant]

Issue: https://pypi.org/project/hpsklearn/

• The pypi package for the project is outdated.
• The project description is incorrect and requires appropriate formatting.
• Perhaps pip install hyperopt-sklearn should be used instead of pip install hpsklearn.

Proposed solutions:

1. Bjkomer updates the project under hpsklearn and will suitably edit the project description and the other information that is displayed.
2. I will add this project under hyperopt-sklearn to pypi and update the project description accordingly.

@bjkomer Any thoughts on this? I think adding @mandjevant as a maintainer in PyPi would be the easiest solution.
