Support for Fairy-Stockfish chess engine and all it's variants?

[numlockkey]

Fairy-Stockfish is a chess variant engine derived from Stockfish designed to support fairy chess variants and easy extensibility with more games.

multiple variants, or at least 960 support would be amazing

There is too much work to be done in classic chess mode, I do not plan to include variant support for now.
