/**
 * The `addHookData` function is responsible for collecting all of the results from the `fetchHookData` function calls
 * and prepares the shape of the data to match what the frameworks expects (such as setting initial values for SWR and collecting SEO data).
 *
 * ## Usage
 *
 * ```ts
 * export async function getServerSideProps(context) {
 *	try {
 * 		const usePostsHook = await fetchHookData(usePosts.fetcher(),context);
 *		const useAppSettingsHook = await fetchHookData(useAppSettings.fetcher(),context);
 *		return addHookData([usePostsHook, useAppSettingsHook], {});
 *	} catch (e) {
 *		return handleError(e, context);
 *	}
 * }
 * ```
 *
 * @param hookStates An array of resolved promises from {@link fetchHookData}
 * @param nextProps Any additional props to pass to Next.js page routes.
