 This function returns a `xr.Dataset` containing the CF fields needed to reconstruct the
 geometries. In particular there are:

 Here are the attributes on `geometry_container`. This pattern mimics the convention of
 specifying spatial reference information in the attrs of the empty array `spatial_ref`.
