Make output_flag.orank configurable for Point-Stat.

[JohnHalleyGotway]

Describe the Enhancement

Issue dtcenter/MET#1764 and Pull Request dtcenter/MET#1885 enable Point-Stat to write the ORANK line type when applying the HiRA verification algorithm. Part of the code changes are adding an entry for orank in the output_flag dictionary. Please see the default point_stat config file.

Note that running Point-Stat with a config file that does not contain output_flag.orank does run fine.

This task is to add orank to the wrapped METplus Point-Stat config file and make its value configurable.

Added this to the beta2 development cycle but it could be moved to beta3 if needed.
