DECODR v1411 pH, DIC, TA export module

DECODR will build a database-friendly csv using a cruise's Dickson-Cervantes pH-DIC-TA csv (spreadsheet export) and sta.csvs. This version adds two pH columns (pH1, pH2) left of the DIC & TA columns (DIC1, DIC2, TA1, TA2).

A slight modification to the DIC record parser - no "COFI" is needed in front of the DIC bottle number in column 1. But, there should be no description lines above the data table - the first line should be the data column headers; lines 2+ are data.
