ideas for stretch goals

1. tag with cars: program a car to move away from another chasing car (probably requires the chased car to stay in frame to make it harder)
2. spelling a word with the car: the april tag as a target give an additional information (orientation), that we can further implement to spell out a word.
3. grid of cameras to widen the effective field of the algorithm
4. multiple vehicle one target: the closest vehicle goes to the target

Ideas will be filtered and properly planned for the rest of the summer
