Description

The following chat events need documentation for the website:

• ChannelMessageActionEvent
   
• BitsBadgeEarnedEvent
• CheerEvent
   
• SubscriptionEvent
• GiftSubscriptionsEvent
• GiftSubUpgradeEvent
• PrimeSubUpgradeEvent
• ExtendSubscriptionEvent
• PayForwardEvent
   
• PrimeGiftReceivedEvent
• RewardGiftEvent

The following API endpoints have been added to Twitch's Helix API docs, but have yet to be implemented in this package:

• Get Extension Analytics (see #9)
• Create Stream Marker (see #17)
• ~[Get Stream Markers]

With the unit tests already residing in the files we are already have a good test coverage, I think.
But for a wholesome API implementation it would be nice to have some integration tests that link with the library the way an end user would.

This will also help us setting up the new Twitch API.
