Compressed image topic not accessible #94

I have two compressed image topics that I am publishing. For example, one is at /robot/cameras/bw/image_raw/compressed. I verified that the topic is subscribed to by /web_video_server by checking rqt_graph.

When I visit http://localhost:8080, I can see the two camera topics listed without any links to click on to navigate to the stream or image snapshots.

Both image topics have camera_info additionally being published, and if I publish the raw_image without compression it seems to work fine.

With the way it's currently implemented, compressed topics won't be listed in stream list, but they still should be accessible if using ros_compressed type stream.

For example, if the camera driver is publishing /camera/image_raw/compressed topic, it can be accessed through this URL:

http://127.0.0.1:8080/stream?topic=/camera/image_raw&type=ros_compressed
