ROS2 branches with Python

[RodBelaFarin]

All ROS2 branches do still include the Python wrapper, which start with importing rospy - so the Python part is still ROS1. I find it quite confusing to have a ROS2 package with non-working ROS1 code inside.

Good point. I went ahead and updated the python code to use ros2: https://github.com/ros-perception/laser_geometry/pull/80
