EventSub Websocket fails reconnect after some time

[Maaster]

Made a tool to track the bits and subs, it works fine overall, but at some point it just fails to reconnect.
The timing of this isnt clear, but it seems to be around 1-3 hours. Happened 4 times so far.

I dont see an immediate trigger, as there is no event that is triggered. Also happened on 2 seperate machines, so I doubt its just a machine or network issue. (This log happened on stream too, as an example)

(Censored some names/ids and cut out a lot of keep-alives)

Loading old data...
Bits file doesnt exist.
Subs file doesnt exist.

asyncio.run(initTwitch())

Omitted the callback functions of the eventsub. If you want, I can post them though.

twitchAPI is version 4.2.0, Python version is 3.10.

This is solved by #310 which has been merged but not released yet
