Sample Point Cloud Task UIs?

Looks like [point clouds](https://docs.aws.amazon.com/sagemaker/latest/dg/sms-point-cloud.html) in Sagemaker ground truth are still new but it would be nice to see some sample UIs to better learn how to customize tasks.

One specific thing I'd like to customize is the ability to color the point cloud based on point attributes. For example, if the format is `binary/xyzirgb` then I'd like to be able to toggle between intensity (i) and color (rgb).
