FR: expose device/sharding argument for NamedArray.wrap

Hm, I'm not sure this is necessary? You can provide the device and sharding for the array before wrapping it, and pz.nx.wrap should preserve it, e.g.

arr = pz.nx.wrap(jax.device_put(my_array, my_sharding))

Yep, just a little syntactic sugar :). When training large models, I often use a data loader to grab data from the disk and process it onto a numpy array, then directly from there convert it to a NamedArray sharded over devices.
