The output of Python's random.randbytes function is predictable. Here's a demo of that.

1. Save the output of mersenne.py.
2. Delete the last 10 elements of that output.
3. Feed that truncated output to mersenne_breaker (cargo run).
4. The output of mersenne_breaker is the same as the 10 elements you deleted.

Tested on Python 3.9.
