VdW B&L ribbons 1Å= step

Chaotic 2LJL dynamics animation. Set a new time step in seconds. Exit/Enter WebXR to change view mode. Tested on Oculus Go (with touchpad). Click trigger button to change control modes. For tests on a desktop (Windows 10 + Chrome) the "inline" webxr session and A,S,D,W,↑,↓ keys for navigation are used.
