Provide properly typed selectors example for CustomSerializer

[moniuch]

Information

When following the instructions for creating a custom serializer, there is no explanation how to provide custom selectors for the returned properties { url, params, queryParams } (as the default ones provided by getRouterSelectors cease to work). It's maybe not that hard to write code that works, the intimidating part for a lot of users might be the proper TS typing.

A good accompanying selectors example for this serializer would be gold. Thank you.
