Revolt API 0.5.3 support.

[insertish]

Since your library uses user authentication, you need to update certain routes. (revoltchat/backend#63)

Revolt's user authentication flow has been overhauled, changes include:

• Completely re-done REST API.
• Deprecation of x-user-id header.

Documentation is available here: https://developers.revolt.chat/api/#tag/Account

Thanks for reminding me - I kind of forgot about the fact that this library exists. I'll definitely implement those changes.
