Move away from reflection for getting shuffled indices from DefaultShuffleOrder

[googol-apps]

As a developer, I want to move away from reflection for getting shuffled indices from DefaultShuffleOrder, so that I can avoid the overhead and risks of using reflection.

Acceptance Criteria:

• The app should implement its own shuffle order class that extends the [ShuffleOrder] interface and provides access to the shuffled indices through a property.
• The app should use the custom shuffle order class instead of the [DefaultShuffleOrder] class when creating or updating the [MediaSource] or the [MediaItem].
• The app should be able to save and restore the shuffled indices using the property provided by the custom shuffle order class.
• The app should handle any errors or exceptions that may occur while using the custom shuffle order class.

Additional Notes:

• The app should follow the best practices and standards for implementing and using the [ShuffleOrder] interface, such as [ShuffleOrderUtil] or [ConcatenatingMediaSource].
• The app should provide a user-friendly and intuitive interface for enabling or disabling the shuffle mode, such as a button or a menu item.
