Pull Request Summary

revert grib2 back to jpeg

Description

This reverts the change made in #1496 If you do a seperate wgib2 command, complex packing does reduce grib2 size, however using the option directly in ww3_grib results in larger files.

Check list

• Branch is up to date with the authoritative repository (NOAA-EMC) develop branch.
• Checked the checklist for a developer submitting to develop.
• If a version number update is required, checked the updating version number checklist.
• If a new feature was added, a regression test for testing the new feature is added.

Testing

• How were these changes tested? regtests
• Are the changes covered by regression tests? (If not, why? Do new tests need to be added?) yes
• Have the matrix regression tests been run (if yes, please note HPC and compiler)? ursa, intel
• Please indicate the expected changes in the regression test output, (Note the list of known non-identical tests.)
  Tests that create grib2 files will have differences as the grib2 packing has changed.
