This bulk download tool provides the NWS text
in a raw form, hopefully directly usable by your processing system.
You can either provide a complete 6-character PIL/AFOS ID or provide
the 3-character base ID (e.g., AFD). The start and end
dates represent 00 UTC for those dates. The Zip format is useful as
the filenames will have the product timestamp, which is useful for
when the product format has ambiguous timestamps.
