Clover - UCI chess engine

3.3
This new release brings various search changes and tuning and a whole other net architecture, having ported my trainer to Cuda: 4x768 - 2x768 - 1.
Every input is mapped according to the king's position, more exactly using this table:
const int kingIndTable[64] = {
0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0,
1, 1, 1, 1, 1, 1, 1, 1,
1, 1, 1, 1, 1, 1, 1, 1,
2, 2, 2, 2, 2, 2, 2, 2,
2, 2, 2, 2, 2, 2, 2, 2,
3, 3, 3, 3, 3, 3, 3, 3,
3, 3, 3, 3, 3, 3, 3, 3,
};
Also, the inputs are flipped in case the king is on the king side, meaning we flip the board so that our king is on the queen side. (Yes, it's a bit weird).
There is also the go san command for a prettier output in SAN mode.
Anyways, this release should be about 60 elo stronger in self-play, at least at STC on a unbalanced book (Pohl.epd to be precised).
