/v1/rows limit when applying a mapping function

The /v1/rows endpoint of the REST API can apply a mapping function to transform the result rows provided in the response. Previously, when applying the mapping function to more than 4096 rows, the request failed with a JS-FROM-LIMITEXCEEDED error. Now, the request can apply the mapping function to 262,144 rows in a single request. Regardless of whether the request applies a mapping function, if the query returns a large number of rows, the client should page over the result rows.
