cleanup: also write gas and setpoint changes in simulator mode
This is related to the previous commit. There is all kinds of logic around
that distinguishes real diving mode and simulator mode. This is valid in certain
cases. For example, we do not want a simulator session to act as a repetitive dive
for subsequent real dives.
What is simply wrong, is skipping relevant logic, like gas switches to act
differently in the simulator and in a real dive. The main advantage of this
commit is code simplicity. Normal users will never see the difference, as
simulator dives are not logged (unless compiled in by a developer).
