Option to load minimal required coordinates and connectivity

[rajeeja]

Proposed new feature or change:

This "minimal" reader would only reads corner nodes and face node connectivity, ignoring other info in grid file. #953

This could be generalized for all other grid formats also.

I can tackle this, when you say corner nodes do you mean just read in the nodes of the grid? @rajeeja

💯 Just be careful, sometimes there will be center nodes, edge nodes also. How to tackle those?

It shouldn't be too hard, I figure we could even use our current readers, but pass in a minimal tag or something, which tells it to only read the face_x/y/z/lat/lon and face_node_connectivity
