Runs three tests:

test_vectors: 472 externally generated vectors from cacophony that cover each pattern * suite combination.
test_negative: tests for malformed protocol names, truncated/corrupted/replayed messages, prologue and PSK mismatches, oversized messages, and state-machine misuse.
test_roundtrip: full handshakes with freshly generated keys.
