On adding windows support

[jhuangBU]

I have tried getting the code to run on Windows and have made decent progress. But unfortunately, I am running out of time, so instead of a full PR, here are the things I have found out:

To get this thing to run on Windows, you need to:

• hack caster.h so the C++ extensions compiles(see https://github.com/facebookresearch/pytorch3d/issues/1024)
• Manually install GroundingDINO using pip(pip install git+https://github.com/IDEA-Research/GroundingDINO.git) before pip install -r requirements
• find a way to get the forked viser to build its client on Windows

good luck!
