/**
 * Handles a single concurrent request and updates the `value` or `error` through the provided `onChange` and `onChangeError` callbacks. The callback in the returned tuple enables issuing a new request. If the callback is called with no arguments, it resets the request back to the `idle` state, aborting the prior request if it was not fulfilled.
 *
 * @deprecated Use `useAsyncProps` instead.
 *
 * @param fetch An optional request fetcher that defaults to using the standard `fetch` method.
 * @param props The optional `onChange` and `onChangeError` callbacks to notify about the resulting `value` or `error`, and the `name`.
 * @returns A tuple consisting of the current request state and a callback to issue a new request.
