It fixes the following issue:

If you use Orb like this:

• Render the graph after which you want to console.log a message and recenter the graph
• After 5 seconds, change the view settings by enabling physics

orb.view.render(() => {
  console.log('Rendering done');
  orb.view.recenter();
});

setTimeout(() => {
  orb.view.setSettings({
    render: {
      isPhysicsEnabled: true,
    },
  });
}, 5000)

The problem:

• When enabling the physics, simulation of the nodes will start
• When the simulation ends, it will call the same callback from the first render (console.log and recenter)

The solution:

• After calling the user's callback, remove it so it is not called anymore in simulation end event
