ex. use when change player view frequently like tableView / collectionView
import MMPlayerView
mmPlayerLayer.playView = cell.imgView
mmPlayerLayer.getStatusBlock { [weak self] (status) in

}
self.mmPlayerLayer.set(url: DemoSource.shared.demoData[indexPath.row].play_Url)
self.mmPlayerLayer.resume()

##PresentedViewController
1. Set transition config
    required init?(coder aDecoder: NSCoder) {
       super.init(coder: aDecoder)
        self.mmPlayerTransition.present.pass { (config) in
            // setting
            .....
        }
    }
2. Set MMPLayerToProtocol on PresentedViewController
3. Set MMPlayerPrsentFromProtocol on PresentingViewController

1.Set MMPlayerLayer
   // roation screen to landscape can change player to fullscreen
   mmplayerLayer.fullScreenWhenLandscape = true
   
2. Set from code
   mmplayerLayer.setOrientation(.landsacpeLeft)
   
3. Observer
  mmPlayerLayer.getOrientationChange { (status) in
        print("Player OrientationChange \(status)")
  }
