Smooth ramping of ATR and Torque Tilt

[surfdado]

This feature has been tested by a handful of riders for the past few months.

Following the example of inputtilt where ramping rates of over 50deg/sec are used, we're doing the same for ATR and Torque Tilt now.

Setpoints are ramped slower when near the current setpoint. This allows for much higher ramping speeds without causing a jerking effect.

Instead of using 5deg/sec and 3deg/sec one can now easily run 20 and 12 or even more without any perceived downsides.
