Enhance duplicate_flag functionality to support summary metrics for multiple observations within a time window. #526

This is functionality most recently requested by Bob Craig at AFWA via MET-Help:

He'd like to use the maximum wind speed observation falling within his time window for verification rather than just the one closest to the valid time of the forecast.


As of met-5.0, duplicate_flag can be set in Point-Stat and Ensemble-Stat to NONE, DUPLICATE, or SINGLE. Enhance it to also support MIN, MAX, UW_MEAN (unweighted-mean), TW_MEAN (time-weighted mean), MEDIAN, PNNN (for percentile), and perhaps BEST (for closest match to the forecast). Although the last one might not be good. [MET-526] created by johnhg

All new observation summary metrics have been implemented and tested. They are NONE, NEAREST, MIN, MAX, UW_MEAN (unweighted mean), DW_MEAN (time weighted mean), MEDIAN, and PERC (percentile) by mccabe
