Write ROS nodes for autonomy sensors.

[Supernova1114]

• [x] Nav X needs a CPP node. (In Progress)
• [X] GPS needs a Python node. (I think I started one if I recall).
• [X] Lidar has a ROS2 package already.
• [X] Zed has a ROS2 package already.
  • Though would like to still write a node that does not require Nvidia dependencies. / see if we can actually get the ros2 wrapper to build on a Pi.
• Realsense camera has a Ros2 wrapper (I have yet to try it out).
