Bans/Banned events who did it
But extended to the Helix API.
It would be useful to add who did a given "Ban Event" to the Get Banned Events for "service restart catchup" when using eventsub.
And useful to add it to the main "get banned users" for determining as a moderator using a tool the history or a user and to check with that moderator why that user was banned, but can't since the API doesnt' report who did it.
