HMAC-based Hierarchical Key Derivation: deterministically derive
a hierarchy of symmetric keys from initial keying material through
repeated applications of the Hash-based Message Authentication Code
(HMAC) construction. Optionally supports storing root derivation
passwords as a 24-word mnemonic phrase (i.e. BIP39).
