How to use the token-types.INT24_BE function in token-types

public get(buf: Buffer, off: number): IStszAtom {

    const nrOfEntries = Token.INT32_BE.get(buf, off + 8);

    return {
      version: Token.INT8.get(buf, off),
      flags: Token.INT24_BE.get(buf, off + 1),
      sampleSize: Token.INT32_BE.get(buf, off + 4),
      numberOfEntries: nrOfEntries,
      entries: readTokenTable(buf, Token.INT32_BE, off + 12, this.len - 12, nrOfEntries)
    };
  }
}
