Describe the Enhancement

The pull request dtcenter/MET#1892 for issue dtcenter/MET#1788 adds a new STAT line type that is created by Stat-Analysis. The SSIDX line type is documented in the Stat-Analysis MET User's Guide chapter on the feature branch. After that PR is approved/merged, please see the develop branch instead.

The SS_INDEX column contains the key statistic. However, there is no way to aggregate this across multiple cases. Instead, we'd just plot this using the summary method (e.g. mean or median). We should also be able to plot it as a boxplot. @michelleharrold and @hertneky can provide additional data for testing and validate the resulting plots.

The columns for FCST_MODEL, REF_MODEL, N_INIT, N_TERM, and N_VLD are purely information and do not need to be plotted.

Please ask @JohnHalleyGotway any questions about how to handle the data.

A sample data file is provided here:
ssidx_sample.tar.gz

One file with FCST_VAR = OBS_VAR = GO_INDEX.
One file with FCST_VAR = OBS_VAR = SS_INDEX.
Another option is CBS_INDEX but no example is provided here.
Note that strings in the header columns can get long. For example, MODEL = fcst model name, reference model name. By default, when multiple strings are encountered in the input, their unique values are written to the output as a comma-separated list.
