[suggestion] check if account has nitro or if has 2 unused boost slots

https://discord.com/api/v9/users/@me/guilds/premium/subscription-slots

if account has no nitro, this API endpoint will return an empty object, else will return the boost slots along with information if they have been used (premium_guild_subscription = null if the boost slot has not been used)

This is something I'd love to see integrated, personally if there was a source available this is something I would've done a while ago.
