[Feature]: Add NWBZarrIO.read_nwb method

[oruebel]

What would you like to see added to HDMF-ZARR?

Add a static method NWBZarrIO.read_nwb() which would accept: 1) local path, 2) S3 path, or 3) an open Zarr store and return the corresponding NWBFile object.

This may also require update to ZarrIO.can_read to handle S3 path's properly.

Is your feature request related to a problem?

This is directly related to NeurodataWithoutBorders/pynwb#1974 with the goal to add a read_nwb convenience function.

What solution would you like?

Do you have any interest in helping implement the feature?
