DM5 Data structure changes

[Rainer Mohr]

Gentlemen,

Last week, Suunto released DM5 which ist still a huge bunch of crap and 
has no evident changes in the UI towards DM4.
However, the database has changed, especially the profile part. Name ist 
still DM4.db though.
The profile data is no longer in the BLOB field ProfileBlob, but now in 
the BLOB field SampleBlob.
In that, you have binary data, which has a new structure.
Each sample is stored in a block of 16 Bytes.
The first 3 bytes are irrelevant.
Bytes 4-7 contain the depth as floating point number (read like in DM4)
Bytes 8-10 contain the pressure (read bytes backwards and convert to 
decimal). result is millibar
Bytes 11-12 contain the temperature in Celsius (read bytes forwards and 
convert to decimal)
The last 4 Bytes are always FFFF7F7F

Example:

                       Depth                 Pressures         Temps

01 00 00       48 E1 BA 3F         CC 49 03          00 0F FFFF7F7F   => 
1,46 meter; 215500 Millibar, 15 Degrees
01 01 00       48 E1 DA 3F        CC 49 03          00 0F FFFF7F7F => 
1,71 meter; 215500 Millibar, 15 Degrees

etc. ........

Just in case you run into new files not importing with the DM4 parser...
