py-minkowskiengine: new package (sparse tensor autodiff by Nvidia) (#35302)

* py-minkowskiengine: new package (sparse tensor autodiff by Nvidia)

This python package (with cuda support) provides torch support for sparse
tensors. The `pybind11` headers are not found without the patch to `setup.py`.

* [@spackbot] updating style on behalf of wdconinc

* py-minkowskiengine: depends_on numpy, pybind11 type=link; no patch

* [@spackbot] updating style on behalf of wdconinc
