[atomic-router] Добавить в freshChain и startChain вторым параметром mapParams

[xaota]

const postQuery = createQuery({ handler, initialData });

chainRoute({
  route: postRoute,
  ...startChain(postQuery), // тут хочется еще сделать mapParams
});

I've investigated it a bit, and I do not think it's possible to implement right now because of TS limitations 👇

However, If you find a way, please let me know, and let's start with a type-tests because it is the most enduring challenge in the proposed API design.
