DESCRIPTION OF CHANGES:

The default ocean resolution for C192 was updated to 0.25-degree.

TESTS CONDUCTED:

The gdas_init utility was run on a 20240806/06z test case on Hera using 05f0120.

CDUMP was set to 'gdas' and CRES_HIRES was set to C192.

The log file indicated that the 0.25-degree 'fixed' files were used. The log file (log.gdas) and the coldstart files from the run were placed here: /scratch2/NCEPDEV/stmp1/George.Gayno/gdas.init/output

DEPENDENCIES:

None.

DOCUMENTATION:

N/A

Without this change, @XuanliLi-NOAA found that for in C384/C192 experiment the first forecast using the generated ICs contained warnings like this:

 61:  warning: layer 1 ice temp is too low:  0.855690983945010
 61:  fix layer 1 ice temp: reset it to:  173.000000000000

When the OCNRES for C192 was set to '025' as in this PR, the warnings were no longer generated.
