Calculates and stores the waste for this result given the cost of change and the opportunity cost of spending these inputs now vs in the future. If change exists, waste = change_cost + inputs * (effective_feerate - long_term_feerate) - bump_fee_group_discount If no change, waste = excess + inputs * (effective_feerate - long_term_feerate) - bump_fee_group_discount where excess = selected_effective_value - target change_cost = effective_feerate * change_output_size + long_term_feerate * change_spend_size
