chore: update README to indicate playAnimation
(suggestion for us lazy copy pasters) if animation file specified through xml it starts playing automatically, thus the true equivalent to setting this in java, would require `playAnimation`
@@ -80,6 +80,7 @@ From a json asset in app/src/main/assets:
LottieAnimationView animationView = (LottieAnimationView) findViewById(R.id.animation_view);
animationView.setAnimation("hello-world.json");
animationView.loop(true);
+animationView.playAnimation();
```
This method will load the file and parse the animation in the background and asynchronously start rendering once completed.
