Allow the user to provide a starting FEN for offline games against stockfish and online challenges. This would be a toggle-able option in the menu (e.g. "Custom position: No / Yes") where "Yes" will show an input field for a FEN (which would then need to be validated before starting any game - note: FEN will need to be validated based on variant selection).
