Ignore automatic setpoint changes during ascend:
In the previous version setpoint changes which have been configured for descending were considered for deco calculation in case one or more additional diluents have been activated.
This procedure does not fit to the common way to keep setpoint high till end of the dive in order to get rid of the deco time.
In the new implementation the OSTC assumes that the current setpoint is used till the end of the dive.
