Package version

Describe the bug

The current build includes AVSession, which is not available on macos. The build breaks on mac since the source is shared between iOS and macOS.

To Reproduce

Steps to reproduce the behavior:

1. on the apps pubspec, depend on the project repo with ref on a6de25f11d07453b8827ba0298cff619cb681e1f
2. Build for macos
3. Build will break with a message similar to:

record_darwin/darwin/Classes/RecordConfig.swift:71:25: error: 'AVAudioSession' is unavailable in macOS
  let audioCategories: [AVAudioSession.CategoryOptions]

Expected behavior

App to build normally

Additional context

One may add consitional declarations to fix this problem:

struct IosConfig {}

#if os(iOS)
extension IosConfig {
    let audioCategories: [AVAudioSession.CategoryOptions]

    init(map: [String: Any]) {
      let comps = map["audioCategories"] as? String
      let options: [AVAudioSession.CategoryOptions]? = comps?.split(separator: ",").compactMap {
        switch $0 {
        case "mixWithOthers":
            .mixWithOthers
        case "duckOthers":
            .duckOthers
        case "allowBluetooth":
            .allowBluetooth
        case "defaultToSpeaker":
            .defaultToSpeaker
        case "interruptSpokenAudioAndMixWithOthers":
            .interruptSpokenAudioAndMixWithOthers
        case "allowBluetoothA2DP":
            .allowBluetoothA2DP
        case "allowAirPlay":
            .allowAirPlay
        case "overrideMutedMicrophoneInterruption":
          if #available(iOS 14.5, *) { .overrideMutedMicrophoneInterruption } else { nil }
        default: nil
        }
      }
      self.audioCategories = options ?? []
    }
}
#endif
