+A smart processing queue that retrieves transactions from blocks with managable concurrency.

+This queue processes the retrieval of block transactions using a limited number of workers to handle potentially overwhelming volume of transactions.
+It wraps the _get_block_transactions function to provide efficient concurrent processing.

+Example:
