Fullscreen orientation (iOS)

You can define how the Player should behave in fullscreen by setting orientation preferences.

1. Using defaultFullscreenOrientation parameter from DMPlayerParameters object passed to create Player in order to set the default orientation when user requests fullscreen.
2. Using the function setFullscreen(fullscreen: Bool, orientation: DMPlayerFullscreenOrientation? = nil) to overwrite the default orientation when programmatically want to switch to fullscreen.
