Bugfix #3429 develop obs_error_table_lookup

[JohnHalleyGotway]

These are the same changes as PR #3430, but for the develop branch instead. Also note that this adds a new unit test to demonstrate the bad observation error table lookup. This is accomplished by truncated the default obs_error_table.txt file to only include the first APCP entry for values between 0 and 0.1. All APCP_24 precip observations outside of this range are excluded from the output of that new test.

Please review this at the same time as #3430, and note the following:

• Find the branch available for testing in seneca:/d1/projects/MET/MET_pull_requests/met-13.0.0/rc1/MET-bugfix_3429_develop_obs_error_table_lookup.
• The following new output test files are created:

ensemble_stat/ensemble_stat_OBSERR_BAD_LOOKUP_20120410_120000V_ecnt.txt

• Compare ensemble_stat/ensemble_stat_OBSERR_20120410_120000V_ecnt.txt to ensemble_stat/ensemble_stat_OBSERR_BAD_LOOKUP_20120410_120000V_ecnt.txt and note that it has fewer lines since there are no pairs for OBS_THRESH = >=2.54 and fewer for OBS_THRESH = >0. As expected, the number of matched pairs in the TOTAL column are greatly reduced for APCP_24 but remain constant for TMP, to which observation error is NOT applied.
