Describe the Enhancement

• MET Enhance Point-Stat to compute SEEPS for point observations and write new SEEPS and SEEPS_MPR STAT line types. #1942 enhanced Point-Stat to write the SEEPS and SEEPS_MPR line types when verifying against point observations.
• MET Enhance Grid-Stat to compute SEEPS for gridded observations and write the SEEPS STAT line type. #1943 will enhance Grid-Stat to write the SEEPS line types when doing grid-to-grid comparisons. Also consider writing SEEPS_MPR information to the "_ncpairs.nc" output file.
• This issue is to extend that grid-to-grid SEEPS vx logic to Series-Analysis as well.

The SEEPS output from Point-Stat and Grid-Stat is configured by setting the corresponding output_flag.seeps and output_flag.seeps_mpr flags. In Series-Analysis, we'll need to add a setting for output_stats.seeps. This is an array of column names for the SEEPS statistics that should be written to the output.

Recommend supporting all SEEPS output columns:

output_flag = {
   seeps = ["TOTAL", "S12", "S13", "S21", "S23", "S31", "S32", "PF1", "PF2", "PF3", "PV1", "PV2", "PV3", "MEAN_FCST", "MEAN_OBS", "SEEPS" ];
}

But please confirm with @RachelNorth that this is correct.

Note that the column names mentioned above have been modified by #2882. Review those changes and update the description above prior to beginning this work.
