Pixel Chess Pieces per Eshlost

Changes default Chess.com pieces to custom beautiful pixelart pieces made by Skemonde. I find it best fits the wooden chess background. Obviously this extension will not pose any risks for chess.com's anti-cheat software (not that I'm aware of any), since it simply changes pieces client-side.
It's my first time making an extension, so with my friend Skemonde's permission, I made it as a little project to teach myself, hope you like it :)
