Support torch==1.9

[ffuuugor]

Hi!
Do you have any plans to support PyTorch 1.9?

We at opacus use csprng to generate cryptographically secure noise and ideally we want to make it available to people using the latest pytorch version.
Additionally, it creates conflicts with the latest versions of packages like torchvision, which makes testing quite tricky

I managed to successfully build and test csprng with torch==1.9.1+cu111. Opacus passes all the tests as well, however I'm not sure csprng is properly covered there.
For some reason the latest release in PyPI (dated in Mar 2021) requires torch-1.8.1. We probably just need to fix the CI.

Well, successfully built csprng in colab (gpu instance) with torch==1.10.0+cu111.

It would be great to have a new release with formal support for PyTorch 2.x and CUDA 12. It builds and passes the tests even with torch==2.4.1 with CUDA 12.4.
