Unexpected spatial referencing in resample_in_space #1163
Description
Describe the bug
When calling resample_in_space(ds, source_gm, target_gm, gm_name="crs", encode_cf=True) and the CRS of source_gm and target_gm are not the same, then rectify_dataset removes the CRS information.
When calling resample_in_space(ds, source_gm, target_gm, encode_cf=True) and the CRS of source_gm and target_gm are the same and the source ds has the spatial referencing in the coords with the name spatial_ref, the returned dataset has the spatial referencing stored in spatial_ref in coords and in crs as data variable.
Expected behavior
For simplicity and accordance with #1013, the spatial referencing information shall be stored in spatial_ref in coords in any case.
