Refactor CMake and enhance API documentation for YAZE

- Updated CMakeLists.txt to set a minimum required version of 3.5 and removed older policy settings for improved compatibility.
- Enhanced yaze.h and zelda.h with detailed documentation, including versioning information and API descriptions, to improve clarity for developers.
- Added new functions for version compatibility checks and improved error handling in the YAZE API.
- Refactored existing structures and enums for better readability and maintainability, ensuring a more consistent coding style.
