[Feature Request] Add support for batched result retrieval executions

Is your feature request related to a problem? Please describe.

Hello,
for some reason need to create the report (CSV) from the ALL workflow execution results, how it looks now:

async function* fetchWorkflowExecutionResults({ workflowClient, namespace, companyId }) {
  let nextPageToken: Uint8Array | undefined;
  do {
        const workflows = await workflowClient.workflowService.listWorkflowExecutions({
            namespace,
            query: `ExecutionStatus="Completed" AND WorkflowType="createCompanyWorkflow" AND companyId="${companyId}`,
            nextPageToken,
        });
        nextPageToken = workflows.nextPageToken;

        for (const wf of workflows.executions) {
          const result = await workflowClient
                    .getHandle(wf.execution.workflowId, wf.execution.runId)
                    .result();
          yield {
            company_id: result.company_id,
            field1: result.field1,
            field2: result.field2,
            another_field: result.another_field,
          };
        }
  } while (nextPageToken?.byteLength);
}

it's working as expected for any amount of the executions, but it takes around ~1min to process 1000 executions, so for 1KK executions -> ~1000 minutes, which is not acceptable for my purposes.

Describe the solution you'd like

For faster processing, I can chunk workflows.executions (e.g., in batches of 50 or 100) using Promise.all(). However, I'm not sure if this is the correct behavior — it might make more sense to add a separate method for this.
