Attempt at solving the Advent of Code 2023 challenge using modern C++ features (WIP).
The code has been developed in Visual Studio 17.9 preview 1.1 and/or g++ 13.1, targeted C++ version is C++23.
At time of writing, it's probably not possible to build this project with older VS versions or other compilers as newest C++ 23 features are being used (for example <mdspan>, construction of containers from ranges with std::from_range, etc.).
