Feature Request: Adding in support for new event sub types

[meant-ion]

STORY: Recently, Twitch has implemented into its EventSub API a lot of different endpoints, including the ability to read chat messages from a channel and marked it as being the preferred method of reading chat messages.

The issue lies with the extra condition field, for example requiring the user_id for the channel.chat.message event. Currently, I do not believe there's a method to include this into the body of the requests for making an event sub listener.

A/C: A way to be able to include the extra field in the body when making the request, so these new endpoints become usable
