Description

There were no unit tests for pointcloud output for QT128 and OT128. I had the opportunity to record some data today and made unit tests. Here's the reference pointclouds:

QT128	OT128

The OT128 was on its head and in a confined space and thus the pointcloud looks a little weird. The output is correct though.
