boolagregate_check pk_msg_list signature returns true if the signature is a valid aggregate signature of the signatures produced by signing message msg (with optional watermark) with the secret key of pk for each element (pk, watermark, msg) of the list pk_msg_list.
agregate_signature_opt sig_list creates an aggregated signature using the list of signatures sig_list.
