hashlib errors on install for windows 11

[jaymedavis]

Just wanted to note a couple things:

1. hashlib won't install on windows 11, it gets an error about unknown OS in setup.py, which doesn't matter much, because number 2....
2. hashlib is included in python now, so it isn't necessary to install

Cheers for the library. I'm new to python, so not only is a fun experiment for seeing how addresses are created, it's been a learning experience for me too. Feel free to close this right away, just figured I'd leave this note here for anyone searching in the future.
