[THREDDS #SGV-570847]: AWS real time chunks

Bradley,

Here's the documentation for the realtime chunks: 
http://www.roc.noaa.gov/wsr88d/PublicDocs/ICDs/2620010E.pdf.

The quick summary of the format is:

[24-byte volume header (for first chunk of file only)][4-byte size of 
compressed data][BZ2 compressed data]

You may be able to use bunzip2 on the compressed data once you pop off the 
other bytes, but I'm not positive; otherwise you'll need to use a function 
that's capable of just handling a bz2-compressed block (no other file metadata)
