Add support for the Aqualung i330R and Apeks DSX

Browse Source 
The Aqualung i330R and Apeks DSX use a completely new communication
protocol. The main (and most problematic) difference is the use of a
proprietary bluetooth pairing mechanism instead of the standard
bluetooth pairing. The data format remains more or less compatible with
the previous models, with only the usual changes to the parser.

The initial code and reverse engineering work was contributed by Janice,
with further improvements and modifications for integration in
libdivecomputer by Jef.
