Dirk Hohndel ae503626ae Shearwater: detect which logbook format is support
The Log Upload RDBI (Read Data by Identifier) response tells us which
format the dive computer supports.

Shearwater recommends to use the 'Petrel Native Format' for all dive
computers which support it, even those pre-Teric models which (depending
on firmware) might support both PNF and the older 'Predator-Like
Format'.

They also recommend to ignore the 0x90000000 format which is very
similar to PNF but without the final record and to use the older
Predator Like Format in that case.

The 0xDD000000 format is never an option by the time you got here, but
in the old code (prior to the PNF addition) we would have fallen back to
0xC0000000, so let's do the same here.

Any other value is actually an unknown format and should be treated as
such.

Which format we use is determined by the base address used to download
the logbook entries.
