Actually, I realized there's a better solution here when implementing the hotspot plugin.

When resuming, simply advance the time forward to the value for `options.end`

So....

```javascript
_setup: function( options ) {
  var self = this;

  // On Playing
  self.currentTime( options.end );
  self.play();
}
```

Make sense? The only issue is making sure that your `end` function handles it appropriately. See https://github.com/mjschranz/popcorn.webmaker.org/blob/ef9559a2a5288dd8fdcb02e7ded41362f54b97cc/public/templates/assets/plugins/hotspot/popcorn.hotspot.js#L406-L414 for an example.
