prepareAsync

Asynchronously prepares the video for playback.

This method sets up the video for playback in the background. Once preparation is complete, the CypressMediaPlayerCallback.onPrepared callback will be triggered. To ensure play() is called at the correct time, invoke the play() method within the CypressMediaPlayerCallback.onPrepared callback. Make sure to implement and register this callback with the player upon its creation.

Ensure the player is valid before calling this method, otherwise it will throw an IllegalStateException.
