[GEMPAK #PVG-756937]: problems decoding ship soundings

Hi Greg-

You need to use the -a option to set the number of extra stations
to add.  The default of 25 is apparently not enough to get all the
other additional stations, plus JCCX.  If I decode just the 
00Z obs from the IDD, -a 25 doesn't  get JCCX, but -a 30 does.
I'd set it to be 40 just to be safe.

Also, the id will be JCCXnn where nn is the synoptic hour of the
report.
