Fetch user boosts

[TheOnlyWayUp]

I want to award users particular roles for the amount of boosts they have. Discord Bots don't have support for this, users can access https://discordapp.com/api/v6/guilds/GUILD_ID/premium/subscriptions which provides this information.

Is there a way I can access this inside of discord.py-self, and, are there any events for boosts & unboosts? (I'm interested in the unboost part, because that's something a bot can't see).

If there are no events, I'd likely iterate over everyone with the server booster role and fetch their boosts every hour or so
