Suunto DM5 Format changed

[Rainer Mohr]

Hi Miika, Linus,

Picking up an old thread from two years back...

I got the first file from the wild with yet another Suunto DM5 format in 
the Profile BLOB field.
This time its blocks of 26 Bytes, no idea what they changed - Maybe a 
new firmware for The EON Steel made that necessary, who knows. 
Detectable by the first Byte being 04. Depths are still in Bytes 3-6 in 
same way as before.

You may want to change that in your DM5 parsing too.

Regards,
Rainer

Case Is = 4
     Return 26
