[Android ]Ask for permission to record before initialize

[Merwan1010]

If you encounter the following error when starting the record :

startRecording() called on an uninitialized AudioRecord

Please make sure to wait for the permission to record before initialize.

  await PermissionsAndroid.requestMultiple([
    PermissionsAndroid.PERMISSIONS.RECORD_AUDIO,
  ]);

  const options = {
    sampleRate: 16000, // default 44100
    channels: 1, // 1 or 2, default 1
    bitsPerSample: 16, // 8 or 16, default 16
    audioSource: 6, // android only (see below)
    bufferSize: 4096 * 2 // default is 2048
  }

  LiveAudioStream.init(options);

Would it be possible to edit the readme.md ?
