Detailed Description

Lazily fetches a single named field of a patch as a numpy array, on demand.

Unlike pdat_to_dic (which eagerly copies every field of a patch to a python dict), this only pays the device->host copy cost for the fields actually queried via operator[]/__getitem__, so a getter that only touches a handful of fields does not force a copy of every field in the patch.
