Oleg Semyonov aad263bdd8 TxPID: enable ramp-shaped throttle-dependent PIDs
Besides of knob PID tuning it is now possible to use throttle channel
to ramp-shape PID coefficients. This can be used to lower some PIDs on
VTOL while sinking to prevent wobble.

To use the feature select throttle as control input, choose throttle
range max and min values, assign the instance to particular PID
coefficient and define a range for it. When throttle is lower than
defined throttle range min value (or higher than max), then min and max
PID values will be used accordingly. Changing throttle from throttle
min to max will linearly scale PID value.

Note that it is possible to set MinPID > MaxPID. In that case increasing
control input value will decrease the PID coefficient.

Up to 3 independent instances can be configured. The number can be
increased changing the UAVO definition, but at the cost of extra RAM.
