What

Make it easier to run the ROS example by adding a robostack-based environment to pixi.

In theory this should work:

pixi run launch-turtlebot

The example can then be run as:

pixi run -e examples-ros python examples/python/ros_node/main.py 

However it looks like the example has bit-rot over time and probably needs some bug fixes.

I've managed to launch rqt_graph too:

Now I'm running into the following issue though:

• error when saving to dot format  ros-visualization/rqt_graph#85
• encode in utf-8 before saving graph dot file ros-visualization/rqt_graph#89
