Sample project: https://github.com/joreilly/FantasyPremierLeague/

Add the following Relation
```
@Query(
    """
    SELECT * FROM team
    JOIN player ON player.name = team.name
    """,
)
fun teamsWithPlayers(): Flow<Map<Team, List<Player>>>
```

I wanted to use Multimap return types
https://developer.android.com/training/data-storage/room/relationships#multimap
to workaround issue https://issuetracker.google.com/issues/341002184 but on iOS it creates a DAO with "import java.util.ArrayList" which obviously doesn't exist.
