Add mean/spread for atmos grib2

[WalterKolczynski-NOAA]

Description

Adds the basic mean and spread grib2 products for the atmosphere.

The new mean/spread files are named according to the new convention, though pres_${grid_type} may be changed to pgrb_${grid_type}. Either way, the input filenames will need to be updated when that change is made. For now, the mismatch means the unlettered grib files result in pres_.

Resolves #2296
Refs #1522

@NeilBarton-NOAA @bingfu-NOAA Can you please review so we can proceed with this PR?

[GwenChen-NOAA]

@JunDu-NOAA is the POC for GEFS atmos ensemble products. He may review this PR too.

I'm not very familiar with this job and files. @EricSinsky-NOAA Do you have any comments?

[EricSinsky-NOAA]

@NeilBarton-NOAA scripts related to ensstat have been added to global-workflow in this PR, which allows for the generation of ensemble mean and spread products. The ensstat program has been added to gfs-utils in PR #52. All the changes in this current global-workflow PR look good.

Testing may be unavailable for days. This PR only adds functionality to GEFS and that has been tested. Moving forward with merge without CI testing.
