This PR changes the handling of notifications - removes the `StreamEvent` and `ReadUpdate` stream - listens on the `OutputRoomEvent` stream in the UserAPI to inform the SyncAPI about unread notifications - listens on the `OutputReceiptEvent` stream in the UserAPI to set receipts/update notifications - sets the `read_markers` directly from within the internal UserAPI Co-authored-by: Neil Alexander <neilalexander@users.noreply.github.com>
