Complete library rewrite and better API for endusers.

Added

• Skyblock models
• Skyblock endpoints
• Added HTML documentation
• More utility functions and support to make it easier and reliable.
• Asynchronous support for discord bot devs and other people to keep it non-blocking.

Fixed

• Rewrote most of the code base.
• Rewrite of the inline documentation.
• Pass API Key as API-Key header so it's secure and follows the standards.
• Refactored the methods to get better support and converted into multiple methods so its cleaner.
• Fixed the tests and the errors / exceptions raised when issues arrive.
• Make the rest of the codebase usable by the endpoint user, if needed. Not compulsary.
