refactor: simplify key derivation logic and improve error handling test: enhance HMAC tests for better coverage and readability
Add a generic initialized auxiliary-function API while preserving the existing digest wrapper. Cover HMAC with a NIST ACVP SP 800-56C Rev. 2 vector and document hash- and HMAC-based usage.

Hi! I added a generic initialized auxiliary-function API to one-step-kdf.
This enables the HMAC-based One-Step KDF defined by NIST SP 800-56C Rev. 2 while preserving the existing digest-based API.
I made these changes for personal use, but they might come in handy.

I tried to keep it as clean as possible.
Thanks !!
