Add errors plots over frames

I added additional plots to understand better in which parts of the trajectory the error is greater.

Instead of computing the average over the frames and plot the errors over the subsequence lengths I computed the average of subsequence lengths per each frame (where the frame considered is the starting point of the subsequence). In this way is possible to see the error over the trajectory and figure out the critical points. The first two plot are about the rotational and translational error over the estimated trajectory. The last 4 are over the frame numbers
