New set of gains for MPCs (for h_ref), new velocities tests in joystick, scripts to eval RMSE, small fix in control cycle eval scripts

Automatic window size for sliding window filtering + Possibility to filter angular velocity (off for now) + v_filt_bis_ is now of size 6 to handle angular part

Put estimated feet position pos_feet_ into currentFootstep_ instead of using desired position footsteps_

Time spent by each block added to Logger + Integration of 15Hz low pass filters in loop + Logging of filtered quantities

Add new Filter class to filter position and velocity quantities given to the MPC (4th-order Butterworth filter to low-pass at 25Hz)

FootstepPlanner prediction of movement is now done with reference velocity instead of current velocity
