[Feature Request] Add an event for automatic channel point redemptions

[TheStaticMage]

Describe the solution you'd like The current channel point redemption code supports custom redeems only. However this does not trigger any events for built-in redeems like highlighting a message or unlocking an emote, or for the bit-based redeems like on-screen celebration or gigantify an emote.

I would like Firebot to support the eventsub "channel.channel_points_automatic_reward_redemption.add V2" as an event and make rewardType a filterable field.

Additional context I did put together some functional code for this, but I'm really not a JavaScript developer and don't really have the time or expertise to submit a production-quality PR to this project. Here's what I hacked together if it might be in any way useful: https://github.com/TheStaticMage/Firebot/pull/1
