Allow to specify coordinate origin

[macrozone]

you can now specify an origin property on the <ARKit /> component with a position.

The whole scene is then shifted, so that {x:0, y:0, z:0} is at that origin.position (which is specified in "absolute" coordinates to the normal origin)

  <ARKit
    origin={{
      position: {
        x: 0,
        y: floorPlane ? floorPlane.position.y : 0,
        z: 0,
      },
      transition: {
        duration: 0.1,
      },
    }}

you can specify a transition as well, so that the changes in the origin.position is animated.

Every intersection-function (hittest, projectPosition, etc.) should respect that new origin and will give coordinates relative to that origin. The original position is also passed as "absolutePosition"

TODO:

• update readme
• check if all functions respect that new origin

readme update will come in another pr
