Pull request overview

This PR adds support for two new cryptographic algorithms to the registry: HPKE (Hybrid Public Key Encryption, RFC 9180) and AES-CMAC-PRF-128 (RFC 4615). However, the PR title and description only mention AES-CMAC-PRF-128, omitting the HPKE addition.

Changes:

• Added HPKE algorithm family with RFC 9180 standard reference
• Added AES-CMAC-PRF-128 variant under the existing AES family with RFC 4615 standard reference
