/**
 * `mapResponse` is a map operator with included error handling.
 * It is similar to `tapResponse`, but allows to map the response as well.
 *
 * The main use case is for NgRx Effects which requires an action to be dispatched.
 *
 * @usageNotes
 * ```ts
 * export const loadAllUsers = createEffect((
 *   actions$ = inject(Actions),
 *   usersService = inject(UsersService)
 * ) => {
 *   return actions$.pipe(
 *     ofType(UsersPageActions.opened),
 *     exhaustMap(() => {
 *       return usersService.getAll().pipe(
 *         mapResponse({
 *           next: (users) => UsersApiActions.usersLoadedSuccess({ users }),
 *           error: (error) => UsersApiActions.usersLoadedFailure({ error }),
