@cerrussell, I have made some improvements to make the project install on windows. But could you also take a look at your convenience?

[cerrussell]

@prabhu This workflow might be helpful for testing the Windows install...
Here's a run on my fork. As you can see, the poetry install runs ok, but chen --download and chen --download --with-science have some issues.

As of now, python 3.8 - 3.10 are able to do chen --download while 3.11 and 3.12 cannot as they can't build a wheel for rocksdb-py.

Chen --download --with-science doesn't work on any of the versions due to not being able to build a wheel for pygraphviz.

Thanks @cerrussell. Have removed rocksdb with this PR. PyGraphviz is a difficult dependency to install on Windows. Scientific work is too difficult for Windows users anyways, so that we can document and focus on Linux and mac users.

Try the new conda-based installer which is working reliably.
