Add support for torch 2.0

[ab3llini]

Scenario summary

Apple Silicon users cannot run zshot due to torch version being pinned to be strictly less than 2.0 ("torch>=1,<2")

Proposed solution

Update torch to 2.0 and release a new wheel on PyPI 🚀

It shouln't really be that hard, I could open a PR if I find some time.

Thank you @ab3llini. I have removed the version constraint, as it should already work with torch==2.0. I will merge the PR as soon as possible.

Regarding a new release, we plan to release a new version soon, but we want to finish some things first. I will ping you when ready. Until then, you can install it from the git master branch:
pip install git+https://github.com/IBM/zshot.git@main
