games-board/fairy-stockfish: new package

Ebuild is based on games-board/stockfish::gentoo

Fairy-Stockfish is a chess variant engine derived from Stockfish designed
for the support of fairy chess variants and easy extensibility with more games.
It can play various regional, historical, and modern chess variants
as well as games with user-defined rules.
For compatibility with graphical user interfaces it supports the UCI, UCCI,
USI, UCI-cyclone, and CECP/XBoard protocols.
