Set up hardware/software for online integration

• install Ubuntu 22.04 on IPK217L (IT)
• clone 'old' code for synergies here
• install nix (python dependencies and ros1/ros2)
  • quickstart here, please don't use the apt-get install nix
  • test your ROS1 and python env from a current ros_datahandler repo, call nix develop .#ros1
  • this same functionality for encoder_dynamics is in progress here, solution will be basically same as in ros_datahandler (should work with latest merge !39 (merged) , tested in #53 (closed))
• optional: set up ROS2 Workspace on IPK217L (should work with latest merge !39 (merged) , tested in #53 (closed))
