feat: Animation improvements fromSpriteSheetCoordinates + EventEmitter (#2666)

This PR adds a few improvements to animations that have been discussed offline 
* Adds new `EventEmitter` type which is a better typed event implementation
* Updates the `.events` type to be the new `EventEmitter`
* Adds the `frameIndex` of the current frame to the animation event
* Adds a new static builder for constructing animations from SpriteSheets 
  ```typescript
   const spriteSheet = SpriteSheet.fromImageSource({...});
   const anim = Animation.fromSpriteSheetCoordinates({
    spriteSheet,
    frameCoordinates: [
      {x: 0, y: 5, duration: 100},
      {x: 1, y: 5, duration: 200},
      {x: 2, y: 5, duration: 100},
      {x: 3, y: 5, duration: 500}
    ],
    strategy: AnimationStrategy.PingPong
   });
   ```
