**example:**

const hexSeed = 'fffcf9f6f3f0edeae7e4e1dedbd8d5d2cfccc9c6c3c0bdbab7b4b1aeaba8a5a29f9c999693908d8a8784817e7b7875726f6c696663605d5a5754514e4b484542';
const { key, chainCode } = getMasterKeyFromSeed(hexSeed);
console.log(key.toString('hex'))
// => 2b4be7f19ee27bbf30c667b642d5f4aa69fd169872f8fc3059c08ebae2eb19e7
console.log(chainCode.toString('hex'));
