Fix packets flagged as unthrottled

 `PacketFlags.Instant` a packet will not be bundled with other packets at a next service iteration and sent instantly instead. This delivery type trades multiplexing efficiency in favor of latency. The same packet can't be used for multiple `Peer.Send()` calls.
 
-`PacketFlags.Crucial` a packet that was enqueued for sending unreliably should not be dropped due to throttling and sent if possible.
+`PacketFlags.Unthrottled` a packet that was enqueued for sending unreliably should not be dropped due to throttling and sent if possible.
