Display a chess position from FEN (Forsyth–Edwards Notation)

Contributed by: Lucien Grondin

ResourceFunction["ShowChessPosition"]["fen"]

displays the chess position fen as described according to Forsyth–Edwards Notation.

ResourceFunction["ShowChessPosition"][]

displays the standard startup position.

Details

The default value for fen is the standard startup chess position. This is shown using ResourceFunction["ShowChessPosition"][].
The produced diagram is a Grid of unicode characters.
All pieces are represented as expressions, not strings. For instance the white king is ♔, not "♔". This might be an issue in a context when these expressions are defined.
