wallet improvements about namada HOT 4 CLOSED

A few notes:

• We should support standard HD deriviation (BIP32), and register a prefix for Anoma soon
• We should support Ledger devices at some point, and potentially other wallets
• We should also support Anoma-specific commands related to validity predicate management

Wagyu looks cool!

Update: the minimum version has been added in anoma/anoma#410.

For testnet, a minimum version would be useful with software wallet with support of:

• managing ed25519 keys (public and secret key)
  • generate new key pair with a user chosen alias (also stored an implicit address derived from it with the same alias)
  • provide a look-up of secret keys from a public key or an alias for signing
• managing addresses (implicit and established address types)
  • generate an implicit address with a user chosen alias (derive from a newly generated key pair that can be stored with the same alias)
  • save established address (created via a transaction) with a user chosen alias
  • provide a look-up of address from an alias
  • provide a look-up of secret keys from an implicit account alias for signing
• persist and read data to/from a (password encrypted?) file
