Pull Request Overview

This PR fixes an issue where the Option class in Discord commands did not correctly resolve type annotations when they were provided as string literals or forward references (e.g., param: 'ForwardRefToSomeThing' or when using from __future__ import annotations).

• Adds support for resolving string-based type annotations using a new resolve_annotation utility
• Improves parameter validation by adding proper type hints and using iterators more efficiently
• Updates import statements to include necessary utilities and remove unused imports

The cache is created fresh for each call to _parse_options, which means annotation resolution results won't be cached across different command parsing operations. Consider moving the cache to a higher scope (instance or class level) to improve performance for repeated annotation resolutions.
