feat(hive): add Hive blockchain support

- messages_hive_pb2.py — generated from messages-hive.proto (IDs 1600-1603)
- hive.py — get_public_key / sign_tx client helpers
- mapping.py — register HiveGetPublicKey, HivePublicKey, HiveSignTx, HiveSignedTx wire IDs
- client.py — hive_get_public_key / hive_sign_tx methods on ProtocolMixin
