Subscription limit exceeded on EventSub websocket reconnect

[Galawer]

If subscribed to more than 5 events that have an associated cost, for example stream.online, resubscribing after reconnecting causes the max_total_cost of 10 to be exceeded and the resubscription to fail.

If subscribed to 10 such events, resubscribing will fail on the first one and cause the websocket to close due to error 4003.
