Improve LOG_DATA visualization

[Peque]

• Have the right sensors displayed as negative values. Then we can imagine the robot walking along the x axis looking left and right and it is more clear when distinguishing events.
• Change angular velocity sign: positive values should be anti-clockwise (needs to be corrected in src/)
• Display the angular velocity below the sensor data so that you can more readily compare sensor events with the turn start and finish
• Have an option to plot with distance on the x axis so that I can eliminate the effect of speed when doing comparisons
