fix: Audio not working in iOS 17 for UrlSource

[andyshephard]

Description

On iOS17, playing audio data via a UrlSource is broken. This is because Apple have modified the AVPlayer and now expect the AVPlayer instance to be initialised with an AVURLAsset housing the data and making use of the newly-introduced AVURLAssetOverrideMIMETypeKey global variable (https://developer.apple.com/documentation/avfoundation/avurlassetoverridemimetypekey?changes=latest_minor&language=objc)

This PR introduces a fix that initialises the AVPlayer instance using the aforementioned method if the user is attempting to load in a data source. If the user instead uses a URL (http://internet.com/file.mp3), it will use the original approach of initialising AVPlayer with the url property.

Original:

playerItem = AVPlayerItem(url: parsedUrl)

New:

let asset = AVURLAsset(url: parsedUrl, options: [AVURLAssetOverrideMIMETypeKey: fileType])
playerItem = AVPlayerItem(asset: asset)

Hello @andyshephard

I have tested your code but I still have the same error 😔

PlatformException(DarwinAudioError, Failed to set source. For troubleshooting, see https://github.com/bluefireteam/audioplayers/blob/main/troubleshooting.md, AVPlayerItem.Status.failed on setSourceUrl, null)

Here is my code, do you have an idea why it still occurs ?

AudioCache? cache;

Future<void> initialize() async {
       cache = AudioCache(prefix: 'res/audio/');
      await Future.wait(Sounds.values.map((sound) async {
        final pool = await AudioPool.createFromAsset(path: sound.fileName, maxPlayers: 5, audioCache: cache);
        _pools.putIfAbsent(sound.name, () => pool);
      }));
  }

Finally instead of create every sound pools at launch, I create it when I need it and it fix my issue 👌 Thanks for your code

Future<AudioPool?> _getSoundPool({required Sounds sound}) async {
    try {
      if (!isInitialized) return null;

      if (!_pools.containsKey(sound.name)) {
        final pool = await AudioPool.createFromAsset(
          path: sound.fileName,
          maxPlayers: 3,
          audioCache: cache!,
        );

        _pools.putIfAbsent(sound.name, () => pool);
      }

      return _pools[sound.name];
    } catch (error, trace) {
      log.e('Failed to create sound pool', error, trace);
    }
  }

Any progress here? I have encountered the same problem on IOS 17, i need to release the app in a very short time so desperately need a fix for IOS 17.
