The FewestCoinSelector class provides a coin selection algorithm that selects the fewest UTXOs required to meet the target amount. This algorithm is useful for minimizing the size of the transaction and the fees associated with it. This class is a sub-class of AbstractCoinSelector | AbstractCoinSelector and implements the AbstractCoinSelector.performSelection | performSelection method to provide the actual coin selection logic.
