[FEATURE REQUEST] Twitch Login

[delasource]

Description

For browser games, especially games that Streamers play with their community, a social login with Twitch would be ideal to have out of the box. Twitch uses a pretty standard and well documented oauth authentication.

Note on the validity time:
User access tokens are valid only for a couple of hours. Maybe less then the match is intended to run.

Context

• Web (react, TS)
