- Migrated to twitch helix api for stream notifications

- Added 2 new fields to creds.yml -> TwitchClientId and TwitchClientSecret
- Users now have to provide them in order to use twitch stream notifications as Twitch is shutting down old api on 18th of February 2022
- Possibly fixed some issues with streams randomly getting cleared
- Added an incomplete trovo stream notification provider
