Implementing the EventSub API

[Teekeks]

EventSub seems to be the future of the Twitch API, aiming to combine the Webhook and PubSub.

Docu: https://dev.twitch.tv/docs/eventsub

Will wait a bit to see where they are going with this before implementing it but planning to implement it.

@Teekeks any update to this?

Webhook subscriptions don't work anymore on v2.3.2

Subscription failed! status code: 404, body: {"error":"Not Found","status":404,"message":"WebSub is deprecated and will be shutdown on September 16, 2021. Applications that have not accessed WebSub before June 16, 2021 no longer have access to WebSub. Consider using EventSub for Webhooks instead. For more information on the WebSub shutdown plan, see https://discuss.dev.twitch.tv/t/deprecation-of-websub-based-webhooks and the EventSub documentation at https://dev.twitch.tv/docs/eventsub."}
