Subject: test: add cross-checked crypto/OTP vectors, unit tests and stricter
 screenshots

- gen_vectors.py: RFC/FIPS/NIST vectors recomputed with Python's stdlib
  (openssl for AES) before use, plus seeded cases around SHA padding
  boundaries, 2038 and 2100; generates test/data/Vectors.mc.
- 31 Monkey C tests (hashes, HMAC, PBKDF2, HKDF, AES, sealed records incl.
  every-byte tamper detection, Base32 errors, 100 OTP and 12 Steam
  vectors, clock, jobs) and a benchmark; pass on all four test devices.
- Screenshot tolerance 0.01 %: one changed character no longer passes.
- Golden images updated for version 0.2.0.
