Update lerp example

[positlabs]

Ideally there would be a simpler way to get an interpolated value. I was using anim.progress before, but that only works for linear interpolation.

A workaround is to animate a dummy object and get the current value from there. Maybe there's a better way. Worst case, we can create some kind of utility function.

anime({
  targets: {x: 0},
  x: 1,
  easing: 'easeInOutSine',
  loop: true,
  direction: 'alternate',
  update(anim) {
    transform.setLocalPosition(vec3.lerp(startPos, endPos, anim.animations[0].currentValue))
  },
})
