Bugfix: Fix Stat-Analysis errors for jobs using the `-dump_row` option and the `-line_type` option with VCNT, RPS, DMAP, or SSIDX

Describe the Problem

This bug arose via dtcenter/METplus#2583. Recommend fixing it in the develop branch for inclusion in the MET-12.0.0 release.

The STATAnalysisJob::dump_stat_line(...) function in stat_job.cc writes output to the file specified by the -dump_row command line option. When -line_type specifies exactly one line type to be written, the header columns for that specific line type are written to the first line of that -dump_row file. Logic is missing for writing header columns for the VCNT, WDIR, RPS, DMAP, and SSIDX line types. Note that WDIR and SSIDX are only written by Stat-Analysis itself. Need to check whether Stat-Analysis can actually read those lines back in as input.

Here's an example error message that's written:

ERROR  : dump_stat_line() -> unexpected line type value VCNT

Expected Behavior

Update Stat-Analysis to support -dump_row dump.stat -line_type ABC for all ABC line types that exist.

Note that WDIR is not a true STAT line type. It is written to the output of Stat-Analysis (similar to -job summary) but it is not formatted as a STAT line type with header columns that can be loaded into a METplus database. As such, there is no need or requirement that WDIR output be read back in as input to Stat-Analysis.

I performed the following testing on seneca:

cd /d1/personal/johnhg/MET/MET_development/MET-develop
 ./test_sa.sh > test_sa.log 2>&1

With cat test_sa.sh:

SA_NB=/d1/projects/MET/MET_regression/develop/NB20240515/MET-develop/bin/stat_analysis
SA_FIX=/d1/personal/johnhg/MET/MET_development/MET-develop/bin/stat_analysis

TEST_OUTPUT=/d1/projects/MET/MET_regression/develop/NB20240515/MET-develop/test_output

for TYPE in `echo "VCNT RPS DMAP SSIDX"`; do
  $SA_NB -job filter -line_type ${TYPE} -dump_row dump_${TYPE}.txt \

done

Writing a dump row file for -line_type of VCNT, RPS, DMAP, and SSIDX all result in an error:

ERROR  : dump_stat_line() -> unexpected line type value VCNT
ERROR  : dump_stat_line() -> unexpected line type value RPS
ERROR  : dump_stat_line() -> unexpected line type value DMAP
ERROR  : dump_stat_line() -> unexpected line type value SSIDX

But with the changes on my bugfix branch, they all produce non-zero output:
