Rijndael, commonly referred to as the Advanced Encryption Standard (AES), is a specification for encrypting data. Solve the challenge to implement this cipher and pass tests.
Create your encrypt function in app.js under encrypt.
This function will be called from the test cases with the following parameters;
byte- The data to encrypt as an array of bytes.
key- The key to use for the encryption, as an array of bytes. The function should return the encrypted data as an array of bytes.

- The data passed will be a single block.
- There will be 3 different sizes of keys passed.
- 128
- 192
- 256
- The cipher mode will always be ECB
- It is allowed to use packages or build-in functionality for this, which means writing your own cipher code is optional.
