This is useful for switching back to the mode indicated by the control
switch after a failsafe or fence breach. I was just changing modes
each time, but it is far more elegant to have a spring loaded switch
for "I am ready to take control again", rather than continually
changing modes.
This patch will boost the target airspeed as necessary to keep the ground speed above a parameter value - param_min_groundspeed. Airspeed is still limited to FBW-max. Setting min_groundspeed to zero (default) disables the feature.
This commit is somewhat temporary as I have come up with a better scheme and will be modifying this. Just making this commit in case I need to roll back
