Delete Multiple Subscriptions in one call
The DELETE EventSub Subscription https://dev.twitch.tv/docs/api/reference#delete-eventsub-subscription takes a single ID, and nothing else (aside from auth etc). I propose allowing multiple IDs to be passed in for a single call, for example id=<id1>&id=<id2>&id=<id3> - potentially up to 100 like other APIs.
This would then unsubscribe from all of the IDs, assuming they pass all the normal auth checks etc.
Currently it takes us 15 calls to unsubscribe from all the subscriptions that we are 'done with', adding up to around 3.5 seconds of time spent round tripping the calls. It seems like there would be a lot of value in making a single twitch api call to do multiple. Fewer auth checks, fewer requests, less data overall being shipped around.
