[BUG] Velocity doesnt go to 0 when stationary

[Quenom]

Describe the bug
when motor is stationary velocity doesnt go to 0

SC60228 sensor

seems like this code is to blame

if (fabsf(delta_angle) > 1e-8f) {
    velocity = delta_angle / Ts;

    vel_angle_prev = angle_prev;
    vel_full_rotations = full_rotations;
    vel_angle_prev_ts = angle_prev_ts;
}

return velocity;

in Sensor.cpp:GetVelocity()
