Add HD wallet generator feature
Add HD wallet generation feature.
Follow the RFC0015 of the Duniter Project.
Some documentation:

What is explained in What are HD Wallets? (Deterministic Wallet) is no HD Wallet.
HDWallet means that:
- if you own a keypair priv/pub, you can derive priv1, priv2, priv3... from priv ; and pub1, pub2, pub3,... either from pub or from priv.
- you can derive either keypairs that can be derived in new keypairs, or keypairs that can't be derived a step further. See the original BIP-32 proposal.
Derive child-pubkeys from a master-pubkey is useful if you make regular transaction with one person, but you want each new tx to go to a new pubkey and not ask this person to this new pubkey each time.
This would be a great improvement in Duniterpy, allowing easy creation of clients with a better level of privacy.
There are algorithms to generate HDWallets for ed25519 keypairs. However, Elois pointed out some of them can be "attacked", and we should chose a relatively new implementation.
Seems like the ristretto algorithm is not subject to the attack pointed by Elois.
