v3.0.1

Version 3.0.1 of <ros-rviz> includes two breaking changes:

• The tfPrefix option of the URDF display has been removed. This was used to visualize multiple robots at once, but now we advise using a package like robot_markers instead.
• The depth cloud display now takes in a topic representing an encoded depth cloud image from depthcloud_encoder. Previously, it took in the names of a color and a depth image topic and called a backend to automatically launch a depthcloud_encoder instance.

<ros-rviz> continues to be pre-release and not recommended for production use.
