Going to go ahead and merge this. I was waiting for NOAA-GFDL/GFDL_atmos_cubed_sphere#405 but that can be pulled in a subsequent PR. |

Description
This PR will add a requested feature that is needed for GFS.v17. The current compression options apply to both the ATM output and for the restart files. A request was made to allow for separate compression options to be applied to the output and the restart files. (In this case, deflate option to the output and zstandard compression to the restart files).
This PR will allow for the compression options to be set separately in the
model_configurefile in UFS.We will still need to discuss whether or not to also have this feature pushed to
develop.This PR will also change the
.gitmodulefiles to point to the production branch made in theatmos_cubedrepo.Issue(s) addressed
