Ed25519 key handling using BIP32 style derivation

Ed25519 is notable for its public key generation involving hashing and bit manipulations, which seemingly prevents its use for BIP32. Instead this package use the ed25519 is extended form (post-hashing).

BIP32 allows derivation given a private key, of up to 2^32 children, using two different derivation scheme (soft or hard).

In soft derivation, the important property is that given the parent public key, one can derive all softly derived children public key.
