TF Tree for Azure is not regulary updating

[ndaley7]

After initialization via the driver, the TF tree for the sensors on the kinect no longer updates. You can see the frame update times on the RQT screenshot that I have included.

To Reproduce
Steps to reproduce the behavior:

1. Start ROS Driver
2. Attempt to subscribe to any of the TF topics in the below RQT screenshot after initialization

Expected behavior
depth_camera_link, rgb_camera_link to be published at regular intervals

Logs
I regularly get "image running behind" warnings, but I am not sure if that is releavant

Seems like it might be an issue with the rate parameter here on line 967:

ros::Rate loop_rate(params_.fps);

Rather than try and hunt down the parameters, im going to add the Azure transforms to the broadcast TF Script
