Add HDR sky lighting support and improve rendering

Browse Source 
Added support for HDR sky lighting, including sampling environment maps with a hierarchical CDF.
Added new utility functions for handling HDR sky data, including memory management and sampling functions.
Added functions to improve texture handling, including pixel data retrieval and texture coordinate management.
Changed the path tracing algorithm to enhance light evaluation from HDR skies and adjust light contribution calculations.
Changed BSDF sampling functions to utilize constants from Common.h for better readability.
Changed the main application logic to load HDR textures and configure the scene with improved lighting settings.
Refactored ray intersection logic to enhance accuracy and performance in triangle intersections.
Adjusted the sample count in the rendering configuration to optimize performance.
Updated the README.md to document new features and example renders.
