Fix the firmware version and serial number

Browse Source 
When downloading a Shearwater Petrel using the predator backend, the
firmware version and serial number are different compared to those
reported by the petrel backend.

This is caused by a difference in the encoding of the data. In the
predator data format, the firmware version appears to be BCD encoded,
and the serial number is stored as a big endian integer.
