add darksidewallet support for GetAddressUtxos

Add a new darksidewallet gRPC to add a utxo that can be returned by the
production GetAddressUtxos, for example:

grpcurl -plaintext -d '{"address":"t1g1HQJuwDoStGrYYLj8VhLu1J5igd8TNXV","txid":"1zjB42Z7FtwRZOBNMlTubCgx9l3dsZSqXxmWpuZXJto=","script": "dqkU8saQsCVS4mNwcByoGCtfOaHFaCiIrA==","valueZat": "3010000","height": "686773"}' localhost:9067 cash.z.wallet.sdk.rpc.DarksideStreamer/AddAddressUtxo

Then the following returns this entry:

grpcurl -plaintext -d '{"startHeight":0,"maxEntries":2,"addresses":["t1g1HQJuwDoStGrYYLj8VhLu1J5igd8TNXV"]}' localhost:9067 cash.z.wallet.sdk.rpc.CompactTxStreamer/GetAddressUtxos

You can also clear the list of entries:

grpcurl -plaintext localhost:9067 cash.z.wallet.sdk.rpc.DarksideStreamer/ClearAddressUtxo
