- Refactored datReader and several other files for code cleanliness - Enhanced runtime performance by optimizing select functions, utilizing std::string_view in place of std::string where appropriate - Removed deprecated filesystem implementation - Introduced Link Time Optimization (LTO) support for Linux builds - Enabled parallel builds for GCC/Clang compilers - Expanded and improved comments for various functions - Replaced version check failure with warning, allowing for continued use with a cautionary message Tested on MSVC/Windows and Clang/Ubuntu
