Pytorch support

[asmeurer]

I am working on adding support for pytorch. A good basis for this work is @pmeier's wrapper code at data-apis/array-api-tests@master...pmeier:array-api-tests:pytorch, and also @AnirudhDagar scipy pytorch demo scipy/scipy@main...AnirudhDagar:scipy:array-api-demo.

Keep in mind I haven't updated my fork in ~6 months.

This was fixed by gh-14. PyTorch support is well-exercised by now.
