This is only used for self-custody lightning. Create the signer macaroon for the watch-only Lightning Network Daemon (LND) node. This macaroon derives from the signer node admin macaroon and is used by the watch-only node to request signatures from the signer node for operational tasks. Returns the updated wallet with the encrypted signer macaroon in the coinSpecific response field.
