Reinstated Data-Source ID in Contouring CSVs in DECODR

CSVs for contour mapping can be generated from different hydrographic data sources: sta.csvs, data reports, IEHs, CTD .asc or .mrk files. A character code is appended to the map csvs distinguishing the various sources: "S" for sta.csvs, "D" for data report, "I" for IEHs, "" for CTD sources. In previous versions of DECODR, the character codes were "turned off" so only map.csvs without the character code were plotted (ie "1607_010m.csv" vs "1607_010mS.csv").

Sta.csvs are the recommended source for contour map data but Data Report are used for derived data plots such as Dynamic Height.

Also changed - when using a Data Report (TXT > csv in DECODR) as a source, the data files previously generated were shallow to deep. But DECODR1703 now inverts the Line.csvs from deep to shallow - horizontal plot csvs are unchanged since they only include one depth such as 10m data

It should be noted that when auto-contouring using DECODR, if the Surfer plot "shrinks" to an illegible thumbnail. It's a range problem with the master file used as a template. I've updated the templates in my C:\CODES\map_masters\ subdir to use local files such as "current_coast_w_islands1.bln" and gridded data from a previous cruise that has been copied to the map_masters subdir.
