Dependency management: a working requirements.txt for demo.py with Cuda

[dgatland]

This repo seems great for running a proof of concept, but it isn't being actively maintained and the environment.yml only contains the direct dependencies, some without pinned versions. By just creating an environment from that dependencies list, I was unable to run the demo.py.

I navigated through various errors and am sharing my requirements.txt with a full set of dependencies in case it helps others who also want to run a quick proof of concept here. This is working for demo.py on my device with Cuda.

Note that I ended up with torch==2.3.1 (instead of 2.1.2)
