Implement alpha-beta negamax. This also removes hope-chess, and commits to the One True Engine. Changes: - PERF: enable optimizations in dev profile as well (otherwise too slow) - PERF: Add config for Cargo to use native CPU instructions when possible - PERF: change from f32 to i64 for evaluation (I don't know if this actually improves anything) - REFACTOR: update material evaluation to be split up more and easier to read - FEATURE: include mobility as a factor in evaluation - FEATURE: implement alpha-beta negamax - REFACTOR: remove hope chess algorithm It is sufficiently strong now to beat me and my wife. We're ~1400 on chess.com, so it's a decent strength but can clearly get better, so future improvements will be fun. I think this will require implementing UCI so that I can pit it against engines.
