[REQUEST] Twitch integration

[liana-p]

Is your feature request related to a problem? Please describe.
We want a twitch integration so games can have streamers play with their viewers voting on some choices

Describe the solution you'd like
Unknown for now, need to look at the API.

In terms of usage, it should probably be an option in choices, like:

choice myChoiceId twitchVoted:
  // ...

So that games can choose which choices are voted on. Once a voting choice is reached, the game would wait until the twitch API resolves whatever it needs to do and returns us the final choice, at which point the game can continue as usual.

Ideally it should show an overlay on screen or something to make it obvious that a viewer choice has started.
