Migrate to Use Array API Standard

[seanlaw]

Aaron Meurer presented a talk at SciPy 2023 regarding leveraging the Array API Standard.

See also this Twitter thread, which provides some references.

As discussed, one could either add the array-api-compat library as a new dependency OR you can vendor it.

Additionally, there are some examples where adoption has occurred:

1. scikit-learn
2. xarray
3. scipy

It isn't clear whether the array API standard is mature enough to be adopted into STUMPY yet.
