Add the ability to manually trigger animations

[WassimHmd]

So i've had this issue where my elements starts coompletely out of view, hidden by an overflow:hidden, and I wanted to trigger the animation manually when the parent arrives through the intersection observer but there was no prop to pass

I'm not sure if I understood your use case. This lib is all about animating elements when they enters the viewport, it does just that.
