v1.1.0

• Seeder functions return the seed. This can be useful (especially in case of the non-deterministic seeder functions) for reproducibility.
• Added C++ constructors for non-deterministic seeders.
• Added installation support for Windows (MSYS2).
  • Should also work on Cygwin and Git Bash for Windows, but I have not tested them.
• Fail with a proper error message if required fixed-width integers are not supported.
• Simplified the installation instructions, which are identical on Linux and Windows (MSYS2).
• Added a security policy.
• C++ benchmark program changed to use a macro instead of templates.
  • The C++ functions are themselves templated, so they cannot be used as templates.
  • Using a macro gives more accurate running times.
• Moved the sudoku generator and solver to the directory containing examples.
  • Made it slightly more efficient by seeding the PRNG only once.
  • Fixed a bug in spacing of displayed sudokus.
  • Renamed the main program from solve_sudoku to sudoku.
• Terminology fix: the functions are called thread-safe (when they use local MT19937 objects) rather than reentrant.
