RangeFinder on NUgus

[ysims]

We want to add a RangeFinder to the NUgus robot. This will allow us to get depth images of the environment. Depth images can be used in the training of networks such as vision. We cannot directly use a RangeFinder in the competition.

The RangeFinder will have similar field values to the main cameras. We want the depth images to line up with the rgb images, so the positions should match.
