Update End-to-End dataset

[javizqh]

The new circuits are different (different walls) and the dataset needs to be updated

[javizqh]

We have updated all of the circuits because we are migrating those exercises to Gazebo Harmonic and we used this chance to fix the walls.

Now these walls are around 1 meter tall instead of 10, so I think this will break the existing datasets for the end-to-end exercise

Hi @javizqh, does it affect the follow line exercise too?

[javizqh]

Yes, it affects the Obstacle Avoidance, Follow Line and End-to-End.

For now it is only the simple circuito, bug hopefully in a week all of them will be changed (reduced walls)
