Perft world leaderboards + engine dev utilities

[Sapling]

I wanted to make a quick post about the recent developments on TGCT (The grand chess tree)

I've added various tools that I hope are useful for engine dev, specifically when building your move generator, including: FEN / PGN / Bitboard visualisers, an online WASM perft tool, and a CLI perft test suite.

I've also started work on 'perftwars' which is essentially a move generator leaderboard (still a WIP), so far it's ranked 13 popular move generators / engines. I've been especially impressed by mperft which clocked in at 171B nps on my test rig (multi threaded + hashing), truly insane performance.

Will happily add any other (cpu for now) move generators / engines people want to see tested.

Nice to see that mperft performance impressed you. I saw from the json files you ran mperft with the --bulk option. You should try the --nullmove option instead, that is faster, using tricks discussed here: viewtopic.php?t=86085.
