Had to recreate the spot forecast request parsing script...it appears to have
disappeared since the last bundle of forecasts I had to deal with.

This script outputs a text file for each day that aggregates the meat of the
forecast request into a csv file that can be easily split.  The only modification
of text that occurs is that the lines describing for what periods a given
variable forecast is requested are converted from 1,1,1 to a binary representation
and then converted to a decimal number 0-7.
