Transaction Worker not async

[0xmaayan]

🐛 Bug Description

When running a batch transaction using the Transaction Worker the events are fired only when the worker has finished its execution instead of while it is executing.

How to reproduce

This event only fires when the worker has finished its execution.

Code snippet to reproduce

aptos.transaction.batch.on(TransactionWorkerEventsEnum.TransactionSent, async (data) => {
    console.log("message:", data.message);
    console.log("transaction hash:", data.transactionHash);
  });

Expected Behavior

Event should fire while the worker is executing async and not wait for the worker to finish
