Splits a single action in to an array of actions
Simplifies flows where multiple actions need to dispatch
// Effect splitter@Effect()splitter = this.actions$.pipe(ofType<LoadAdminUser>(UserActionTypes.LoadAdminUser),flatMap(add => [new LoadUserById({ id: add.payload.id }),new LogOperation({ loggedAction: add.type, payload: add.payload })]));
Must use flatMap or NgRx will throw an error
