Audio Delay Cause Player State Wrong

[Paladinfeng]

KSPlayerState.playedToTheEnd Not Call When Video Play Finished

Code In Demo：

let options = KSOptions()
options.audioDelay = -5
objects.append(KSPlayerResource(url: URL(fileURLWithPath: path), options: options, name: "本地视频", cover: nil, subtitleURL: nil))

To support AirPlay, I have to manually delay audio for 2s

let currentRoute = AVAudioSession.sharedInstance().currentRoute
        
for output in currentRoute.outputs {
    options.audioDelay = output.portType == .airPlay ? -2.0 : 0.0
}

Still has bug

func player(layer: KSPlayerLayer, currentTime: TimeInterval, totalTime: TimeInterval)

In this function, currentTime larger than totalTime if I delay audio
