The skill-score is no longer being calculated in the srw_metric.sh test

[MichaelLueken]

Expected behavior

The current .cicd/scripts/srw_metrics.sh test should successfully run and compute the skill-score from the output.

Current behavior

The skill-score isn't being calculated because the data in the Indy-Severe-Weather.tgz file was created using release-public-v2.1.0. The postxconfig-NT-fv3lam.txt control file was updated with the version of the ufs-weather-model and UPP that were merged into develop at 87b26cc, replacing PRSML with MSLET, which is now causing the skill-score to not be calculated for PRSML (or MSLET, both pressure variables were tested and both fail to calculate the skill-score).

Machines affected

This affects all machines.

Steps To Reproduce

1. Clone the develop branch.
2. Set the necessary variables to run the Jenkins srw_metrics.sh script:

export WORKSPACE=(path of your ufs-srweather-app folder)
export SRW_PLATFORM=(e.g., orion)
export SRW_COMPILER=(e.g., intel)
export SRW_PROJECT=(e.g., epic)

3. Run the srw_metrics.sh script - ./.cicd/scripts/srw_metric_example.sh
4. Instead of a value, the script will return SS_INDEX, while giving warning messages that the skill-score couldn't be calculated for two fields.

Detailed Description of Fix (optional)

To get around this issue now and allow the skill-score to once again get calculated, PRSML will need to be removed from parm/metplus/STATAnalysisConfig_skill_score. While working the SRW release in PI15, if we can replace the release-public-v2.1.0 data with data that uses the updated postxconfig-NT-fv3lam.txt file, then we should be able to add pressure back as MSLET.
