Passing intersection observer entry along to modifier callbacks

[gmurphey]

I have a case where it would be beneficial to have the intersection observer entry in my in-viewport modifier callbacks.

@action
entered(_, entry) {
    const targetInfo = entry.boundingClientRect;
    const rootBoundsInfo = entry.rootBounds;

    if (targetInfo.bottom < rootBoundsInfo.top) {
      // do some things
    }
}

<div {{in-viewport onEnter=this.entered}}></div>

It turns out I did this very same thing on #278 and I didn't notice there was an open PR for this very same thing. This can be closed now.

FYI it has been released already.
