Create packages (ros2 pkg create)

ROS2 has a tool to help create package templates. We can get all available options by running

ros2 pkg create -h

which outputs a list of handy options to populate the package template with useful files. Namely, the four emphasized ones.

 usage: ros2 pkg create [-h] [--package-format {2,3}] [--description DESCRIPTION]

                        [--build-type {cmake,ament_cmake,ament_python}]
