Implements a better method of determining when to switch from velocity to altitude control to keep height limit from being exceeded.
This method removes the overshoot and transients in height caused by the switching of the previous algorithm.
The correction for stopping distance applied to the maximum altitude limiter uses the vertical velocity estimate and gives the same offset for both positive (down) and negative (up) velocity.
This calculation has been corrected and simplified and variable names changes to make the functionality clearer.
Both IO and FMU are connected to the safety switch for default models. This needs later to be broken out to a config option for builds that do not contain an IO.
