getCodecname() allows for simple display of the used codec,
getCodec() together with the exported enum of codec values allows for
user defined codec names like this stupid example:
  switch (audio.getCodec()) {
    case Audio::CODEC_M4A:
    case Audio::CODEC_AAC:
      Serial.println("AAC codec!");
      break;
    case Audio::CODEC_FLAC:
    case AUDIO::CODEC_OGG_FLAC:
      Serial.println("FLAC!");
      break;
  }
