Enhances iOS MSL CBOR decoder for multi-item parsing, iOS-specific payload
handling, and IV extraction from ciphertext. Updates NetflixCrypto to support
Tweak-format key JSON. Extends the Tweak to capture DH key exchange material
and session keys more reliably, saving full key histories and implementing
better appboot phase tracking. Adds scripts for DH-derived HKDF parameter
analysis and appboot key response investigation.
Improves documentation on iOS CBOR MSL protocol differences, decryption
pipeline, and key extraction workflow.
Relates to iOS MSL traffic analysis and decryption research.
