Add ability to customize recorder parameters

[hyochan]

Closes #101

Implement ability to add parameters to recorder to customize audio quality.

    const audioSet: AudioSet = {
      AudioEncoderAndroid: AudioEncoderAndroidType.AAC,
      AudioSourceAndroid: AudioSourceAndroidType.MIC,
      AVEncoderAudioQualityKeyIOS: AVEncoderAudioQualityIOSType.high,
      AVNumberOfChannelsKeyIOS: 2,
      AVFormatIDKeyIOS: AVEncodingOption.aac,
    };

    const uri = await this.audioRecorderPlayer.startRecorder(path, audioSet);
    this.audioRecorderPlayer.addRecordBackListener((e: any) => {
      this.setState({
        recordSecs: e.current_position,
        recordTime: this.audioRecorderPlayer.mmssss(
          Math.floor(e.current_position),
        ),
      });
    });
