Walleye is not able to checkmate with king and rook and gets into a loop #16

For the following input command: ./walleye -P -f '4k3/8/8/8/8/8/8/4K2R w - - 0 1' The engine is unable to checkmate and also gets into an infinite loop where the threefold repetition rule seems not to apply.

This is because walleye has no end game table base which is something that would likely give it a good elo bump if implemented. Or if you put it in a gui and gave it more time it would likely find the mate, IIRC its 1 second per move in the CLI version, I also don't think draws or checkmate terminates the CLI version which is something that should be fixed
