feature, debug: make simulator write a logbook entry
When compiling the code with -DSIM_WRITES_LOGBOOK, the simulator writes
to the logbook. This is for debug purpose only. This commit does *not*
define this SIM_WRITES_LOGBOOK, so when compiled, things are functionally
unchanged.
Caveat 1: a simulator generated log cannot be advanced with +5 min. It needs
to run in real time.
Caveat 2: The generated log is currently not "complete". For example, CCR
setpoint switches are not logged. There are likely more small events not
logged. This means that a sim generated log is not a full replacement for
real dive testing.
