creates a 14 column dataset for output

The entire dataset of Environment Canada has 25 columns of data: Tmax,Tmin,Tave, quality flags and other climate data. For use with the package RghcnV3 a 14 column format is required. This format is similar to the 14 column format of GHCN V2. Id is in the first column, followed by Year, followed by 12 measures, one for each month of the year in column 2. This function takes a column and creates a dataset in that format
