Modifications to the evaluation process of daily RDAHMM

Previously, the evaluation process of daily RDAHMM only takes a station's GPS data from 2006-10-01 to "today" as input.

We now extend the evaluation input to include all of a station's GPS data since 1994-01-01; i.e., including input data in the modeling process. For any specific station, the state change sequence in the evaluation process for the modeling time section is expected to be the same as the sequence in its modeling result. Further, if any input data is missing between the last "data-available date" of the modeling time section and the first "data-available date" in the evaluation time section, data duplicated from the last "data-available date" of the modeling time section is used to fill the "data-missing" section.
