Add ScheduledEvents support

[connorshea]

Summary

I think I've got most of this working now, and I've tested it with my own bot. The only thing that isn't working is the event handlers, because I didn't add them to handle_dispatch. I might need some help on that part.

TODO:

• Finish the relevant event handling to handle_dispatch so the event handlers actually get triggered.

---

Added

• Discordrb::ScheduledEvent class to represent Discord's Scheduled Events functionality
• Add a scheduled_events method on Discordrb::Server to get scheduled events for the given server.
• Add a scheduled_event method on Discordrb::Server for getting individual scheduled events.
• Add a delete method on Discordrb::ScheduledEvent to delete the ScheduledEvent.
• Add request methods to Discordrb::API::Server for creating, updating, and deleting scheduled events. These aren't exposed on the Discordrb::Server class right now, but you can use the "raw" endpoints if you really want to.
• Add event handling for ScheduledEvent creation, updating, and deleting.
• Add event handling for users being added and removed to ScheduledEvents.
• Add support for the ScheduledEvent intents.

Hey @connorshea; was this something you were still working on? I have a use case for what you've built here. Not sure if I can be of any help, but I'm happy to get my hands dirty if you'd like!

Interested if anyone is going to pick this up? Is it close? I can look at it if nobody is owning it but it's lots of context to pickup if someone already has the context. Looks unfinished in https://github.com/shardlab/discordrb/issues/183

I'm using the REST api with the bot token for now, if anyone has the same requirements as me, but it's messy and not well integrated.
