Bugfix: fix initial CNS data in the logbook header Apparently, there has been confusion in the past about the data format of the CNS data in the logbook. This seems to be partially fixed back in 2015, but this fix forgot that the initial CNS data is also in the logbook header. So, now, the logbook header also stores the initial CNS data in a correct way, which fixes the problem of strange CNS values at the very start of repetitive dives, that get reset in the dive profile after the first CNS sample data comes along.
