Send commitment_signed batch for splicing
A FundedChannel may have more than one pending FundingScope during splicing, one for the splice attempt and one or more for any RBF attempts. When this is the case, send a commitment_signed message for each FundingScope and include the necessary batch information (i.e., batch_size and funding_txid) to the counterparty.
