Suunto DM5 Format changed

[Rainer Mohr]

Hi Linus,

Yep, this works, the last 4 bytes of each 23 Byte pattern are binary 
floating point numbers that actually correspond to the detailed profile 
data that DM5 shows.
The old pattern was blocks of 16 bytes (without the 7 Byte header 
block), where the depth data was in bytes 3 to 6.

Now I need to find a way to find out which format the SampleBlob uses 
(new or old) as no indication is in the DB data, but that shouldn't be a 
problem.

I'll implement the new data import at divelogs.de tomorrow, @Miika: this 
might be something for you too :-)

Nice one, thanks Linus :-)

Rainer
