Adding BeamNG example

[sidtalia]

Adding a BeamNG in-the-loop example.

This example is a bit heavy on the dependencies, so I'm not expecting the PR to review whether it works; I've ensured on my end that if BeamNGRL is installed correctly and is on the right branch, then the example should work.

This example runs the planner in the background using torch multi-processing and allows the MPC and Planner to work asynchronously (as it would on a real system) while being run from the same Python script.

Places where feedback could be useful: is the README + code sufficiently clear on how someone would use the planner in the loop (if it had to be run from the same python script)? Do I need to explain parts of the code/places where comments would be useful.

• termcolor error

• scipy not found

• psutil not found

• The code does not seem to work on MacOS at the moment. It is unable to find the boost header library

• (GENERAL CODE COMMENT / NOT SPECIFIC TO BEAMNG) I see some sys.append calls in the code. I think it is better practice to have the modules installed as part of the pyproject or setup.py. Try to avoid these workarounds for importing
