Motion processing

The IMU currently provides raw observations from the motion engine, but these are simple accelerations and gyro rates, and do not provide any information that might be used to correct or augment the data being collected. It’s unlikely that this could be improved on-device, but there should be a module in the cloud processing to do so.
