 It is often practical to split larger messages into frames that can be individually decrypted and verified. Because every frame needs a different key, we employ the `nonce_increment` utility function to produce sequential nonces for each frame. As for the AEGIS algorithm, each frame is a completely independent invocation. The program will each time produce a completely different random-looking encrypted.bin file.
