Add ravijo/ros_openpose. Read description, please. (#2217)

The previous repository, i.e., [ildoonet/ros-openpose](https://github.com/ildoonet/ros-openpose), seems dead. So, instead of adding the new repository, i.e., [ravijo/ros_openpose](https://github.com/ravijo/ros_openpose) in this commit, I updated the previous one.
