How to use the token-types.INT32_LE function in token-types

get: (buf: Buffer, off: number): IFormatChunk => {
    return {
      formatVersion: Token.INT32_LE.get(buf, off),
      formatID: Token.INT32_LE.get(buf, off + 4),
      channelType: Token.INT32_LE.get(buf, off + 8),
      channelNum: Token.INT32_LE.get(buf, off + 12),
      samplingFrequency: Token.INT32_LE.get(buf, off + 16),
      bitsPerSample: Token.INT32_LE.get(buf, off + 20),
      sampleCount: Token.INT64_LE.get(buf, off + 24),
      blockSizePerChannel: Token.INT32_LE.get(buf, off + 32)
    };
  }
};
