Implement state machine in the simulator

In std_run the state machine is defined and its relation with the ode selection is implemented.

In run_ADA a flag for apogee deteciton and altitude trigger is implemented and exposed thorugh std_subsystems (to do this a new altitude confidence threshold is implemented in each mission config file).

For the state trasition, ada apogee detection and altitude trigger are now used instead of relying on ode data.

Some flags have been removed as they are not needed anymore
