Upgrade to spack-stack 1.6.0

[DavidHuber-NOAA]

UFS_Utils should be upgraded to use the newest suite of spack-stack libraries (version 1.6.0). This includes an upgrade of CRTM to 2.4.0.1, netcdf-fortran to 4.6.1, and prod_util to 2.1.1. This has already been tested successfully on Hercules on a test build of spack-stack, though official installations have not yet been rolled out.

@GeorgeGayno-NOAA The c96_viirs.bnu grid_gen test is failing on Jet with the error

forrtl: severe (28): CLOSE error, unit 15, file "Unknown"

when the program is stopped at line 165 of mtnlm7_oclsm.F. Looking through the code, I do not see any point where unit 15 is opened, though it is read at line 598. This seems like a bug, though Hera and Orion ran the test successfully. Is this a known issue?

I have not heard of the problem before. Just curious if you are you able to run the head of 'develop' on Jet successfully.

Running the develop branch does not produce the error. I'm going to run the spack-stack branch once more to see if this is intermittent or easily reproducible with the newest library versions.

Indeed, the job passed the second go around, so it seems to be intermittent. I will open an issue.
