Repetition detection and game results' detection

[winapiadmin]

Normal repetition detection is pretty kind of slow when iter the whole move stack per move?

[winapiadmin]

it just can't be faster.... except if you're only looking for perft-only.

See

            p.doMove<false>(m);

(https://github.com/winapiadmin/chesslib/blob/main/examples/perft_with_tt.cpp#L36)

There's still some APIs that need to be implemented for repetition results and game results.

Some game results' detection were implemented in favor of python-chess API, but not the checkmates.
