better handling of type 6 unhandled FID entries
When there are unknown FID values in type 6 messages for DAC values that
have some known FIDs (DAC 200, 235 and 250), the data is not read (and
thus printed as all zeros). I have added some example AIVDM messages
which exhibit this problem, some that did not have the problem in the
existing version and a patch for the problem.
Added sample

adjusted loop logic to allow it to continue to process other types
