Add support for parsing the compass bearings

Browse Source 
When no compass bearing is set on the dive computer, the stored value is
initialized to zero. Since this can also be a valid value, those zero
values are only ignored untill another non-zero value is present.

In later firmware versions, the value will get initialized to 0xFFFF
instead.
