v2.0.0

C++23 rewrite by @arturbac

• version 2.x breaks backward compatibility with version 1.x
• version 2.x has much more constraints for validity of types checking at compile time compared to 1.x and exploits C++23 standard
• all math functions are now available as both plain functions in namespace fixedmath::func and function objects in namespace fixedmath::fobj so they can be utilized with ranges transformation algorithms
• now workflow testing is done for clang libstdc++, clang libc++, gcc, msvc, msvc clang-cl compilers
