Pull Request Overview

This PR adds a new tool ("GetLargeTxs") to the jsutils command, which allows users to retrieve large transactions within a specified block range. Key changes include updating the default value of the "turnLength" option, introducing a new "gasUsedThreshold" option, and implementing the new getLargeTxs function along with its integration in the main command handler.

• [nitpick] The CLI option '--num' is used in multiple commands with potentially different meanings. Consider using a more descriptive name (e.g., '--blockCount') for commands that process block ranges to avoid confusion.

const size = parseInt(program.num) || 100;

[Copilot]

[nitpick] Consider retrieving transaction data in parallel (e.g., by collecting promises and using Promise.all) instead of awaiting each transaction sequentially to improve performance.

	const txData = await blockData.getTransaction(txIndex);
	if (txData && txData.gasLimit >= gasUsedThreshold) {
	potentialTxs.push(txData);
	}
	}
	const transactionPromises = [];
	for (let txIndex = 0; txIndex < blockData.transactions.length; txIndex++) {
	transactionPromises.push(blockData.getTransaction(txIndex));
	}
	const transactions = await Promise.all(transactionPromises);
	transactions.forEach(txData => {
	if (txData && txData.gasLimit >= gasUsedThreshold) {
	potentialTxs.push(txData);
