Crypto CLI Update

I wanted to post a quick update on my command-line tool project for fetching cryptocurrency data. I found the original Java implementation to be too unwieldy and verbose, and I wanted to get more Python experience, so I ported the project over.

I have implemented almost all the same features as the original project in fewer lines of code. I also released the project to PyPI for others to easily install via pip. I plan to keep building new features on the Python version while the original Java project is put on the backburner.
