Allows control of Loki via a Joystick, such as an Xbox 360 gamepad, via ROS2 and pygame.
This package depends on loki_hw_interface, which can be found in our organization's repositories
and must be present (and have been compiled) in the same ROS2 workspace.
Other than being ran manually via the included launch file, copying
scripts/joystick_controller.service to /etc/systemd/system/ allows the script to automatically
run on bootup, provided that you also enable (and start) the service:
sudo systemctl daemon-reload && sudo systemctl enable joystick_controller.service && sudo systemctl start joystick_controller.service
