Exploring key/pair derivation on some nsec/npub concepts that would allow some pretty flexible use cases and lead to some helpful nips that could improve on the current basic key-pair. Preview sketches attached.

PROGRESS:
✅ Initial thoughts for developing use cases.
🟩 define the secure key derivation method.
🟩 Write up a Nostr Improvement Proposal (NIP) draft.
🟩 Share sketches and ideas with the Nostr community for feedback.
🟩 Partner with dev on application to explore isolated user-friendly key mgmt implementation.

NSEC - Nostr Secret Key.
NPUB - Nostr Public Key.
NSUB - Subordinate NSEC with revokability. A unique NSEC derived from an NSEC that generates the same NPUB as originating NSEC.
MSEC - Multi Secret Key. An NSEC derived from an NSEC that results in a unique NPUB.
MPUB - Multi Public Key. NSEC derived NPUB series to have multiple NPUBs on an NSEC.
