Migration to torchviz2

[leo-ware]

As was mentioned in #83, this package is breaking with python 3.12, and it appears to be abandoned by the original maintainer. I've fixed the issue and republished the package as torchviz2.

So, just run:
pip install torchviz2

And then, this will work:
import torchviz
