Describe the Enhancement

This issue arose in testing by @georgemccabe for dtcenter/METplus#1223.
He found that even though the python embedding script he ran in ascii2nc returned bad status, the ascii2nc tool itself did not.

Modify the logic on

Here's some input from @georgemccabe about what/how to test:

In this command, the Python script crashes but ascii2nc does not error (you'll likely need to change the output path):

/d1/projects/MET/MET_releases/met-10.1.0-beta3/bin/ascii2nc "/usr/local/METplus/parm/use_cases/model_applications/convection_allowing_models/Point2Grid_obsLSR_ObsOnly_PracticallyPerfect/read_ascii_storm.py /d1/projects/METplus/METplus_Data/development/feature_617/model_applications/convection_allowing_models/practically_perfect/200205_rpts_filtered.csv" /d1/personal/mccabe/out2/model_applications/convection_allowing_models/practically_perfect/StormReps.2020020500.nc -format python -v 2

This command succeeds because the file exists:

/d1/projects/MET/MET_releases/met-10.1.0-beta3/bin/ascii2nc "/usr/local/METplus/parm/use_cases/model_applications/convection_allowing_models/Point2Grid_obsLSR_ObsOnly_PracticallyPerfect/read_ascii_storm.py /d1/projects/METplus/METplus_Data/model_applications/convection_allowing_models/practically_perfect/200205_rpts_filtered.csv" /d1/personal/mccabe/out2/model_applications/convection_allowing_models/practically_perfect/StormReps.2020020500.nc -format python -v 2

In general, we let the user's python script determine the error condition. If handed bad status, ascii2nc should error out. Note though that retrieving 0 observations from a python script should not, as a rule, be considered an error. For example, finding 0 storm reports on a given day may not be an error. But if the python script cannot be run or it is run and returns bad status, ascii2nc should error out.

For this issue, test as many combinations of bad behavior as is reasonably possible.
