Add support for ascent rate warnings.

Browse Source 
The Cressi Leonardo does store an indicator for the ascent rate (e.g.
the number of arrows) in the upper two bits. This results in 4 possible
values, ranging from 0 to 3, with the following interpretation:

    0.0 -  3.9 m/min  No signal
    4.0 -  7.9 m/min  1 Arrow
    8.0 - 11.9 m/min  2 Arrows
   12.0+       m/min  3 Arrows (with STOP icon)
