Update README and PAYMENT_RECIPES for shipped AES DUKPT and removed op

Browse Source 
README:
- Added DUKPT AES key derivation to current coverage (ANSI X9.24-3, 12-byte KSN, AES-128)
- Expanded DUKPT TDES line to include standard/KSN details for clarity
- Removed AES DUKPT from Future extensions (it shipped)

PAYMENT_RECIPES:
- Replaced "deprecated" with "removed" for Translate Payment PIN Data (issue #4 was resolved)
