Refine timestep
...
1. Solve for 0-crossing in vertical velocity, vertical acceleration
2. Limit timestep to next event
3. Revert to using acceleration instead of jerk to limit timestep
4. Save calculations (eg calculate acceleration) in FlightData at start of timestep, results (eg velocity, position) at end of timestep

Flight data reflecting conditions at the start of the simulation step should be placed in the flight log at that time; new data created during the simulation step should be placed after.

Update unit tests
...
The Falcon 9 Heavy test rocket isn't aerodynamically stable, so allowing the sustainer to tumble before apogee causes an immediate TUMBLE_UNDER_THRUST abort. So, this commit adds a new rocket with a sustainer, core booster, and two side boosters that is stable.

allow sustainer to tumble before apogee.
...
I don't know if it's actually possible for the sustainer to tumble when not
under thrust (I guess it would need a tractor motor and very careful CG-CP design so it would tumble immediately after burnout?) but the conditions are checked separately just in case

[ #2435 ] Copy stageMap instead of directly referencing it
...
This change is to ensure that the stageMap property of the Rocket class is isolated from its source object. Previously, it directly referenced the stageMap of the source, but now we create an entirely new ConcurrentHashMap to hold those stages. This will prevent possible conflicts and unwanted modifications to the source stageMap.
