Optional (Brightcove Player SDK for Android 8.1.1 API)

java.lang.Object
- com.brightcove.player.data.Optional<T>

Type Parameters:

T - the expected type of the nullable value.
```
public class Optional<T>
extends java.lang.Object
```
Optional wrapper can be to pass nullable value safely through RxJava2 stream. Though Android supports this construct since API level 24, using it is not viable because the SDK has to support lower API levels.
