OSTC3: set initial setpoint in profile data
OSTC3: set initial setpoint in profile data

In CCR fixed setpoint mode of the OSTC3, the initial setpoint at the start
of the dive was not set. This fix adds the initial setpoint based on
the data in the fixed setpoint table (ie, the first fixed setpoint is
the initial one).
