Add pytorch 1.13.1 compatibility

[scal444]

When torch 1.13.1 is installed on my machine, and I try to pip install a package with functorch as a dependency, the functorch 1.13.0 package is found and requires downloading of torch 1.13.0. Since functorch >= 1.13 is a dummy package, I'd guess all that's needed is updating pypi

That's a good point. We'll fix this soon.
