Describe the Enhancement

This issue arose via dtcenter/METplus#2476 discussion from @robdarvell.

The OBTYPE stat header column is populated based on the message type specified in the Point-Stat and Ensemble-Stat configuration files. The same OBTYPE string is written for all STAT output line types generated by each verification task, including the matched pair (MPR) and observation rank (ORANK) line types.

However, the message_type_group_map configuration option enables multiple input message types to be grouped together into the same verification task. In Rob's example he's grouping both AUTO and MANU message types together into a group named SURF. Rather than setting OBTYPE to SURF in output MPR lines, he'd prefer to write the input obtype name instead.

This task is to enhance the Point-Stat and Ensemble-Stat tools where the message_type_group_map is involved in the setting of the OBTYPE output column. Provide the option of writing OBTYPE for the MPR and ORANK lines using the original input message type rather than the mapped name of the group.

Recommend adding this logic through a configurable option rather than making a wholesale change:
obtype_as_group_val_flag = FALSE
Where FALSE (default) maintains the current behavior of writing SURF, and TRUE would write the original observation message types of AUTO of MANU instead.

This would support the MetOffice usage without changing the output for others.
