* Add Room Aliases tests

* Add Rooms table test

* Move StateKeyTuplerSorter to the types package

* Add StateBlock tests
Some optimizations

* Add State Snapshot tests
Some optimization

* Return []int64 and convert to pq.Int64Array for postgres

* Move []types.EventNID back to rows.Next()

* Update tests, rename SelectRoomIDs
