Substrate companion: Authority discovery multiple peer ids (#4295)

Browse Source 
* Substrate companion: Authority discovery multiple peer ids

Authority discovery before had a fixed mapping from `PeerId` to
`AuthorityId`. This wasn't correct, as a `PeerId` can actually map to
multiple `AuthorityId`s. The linked Substrate pr fixes this.
