[fen] shortcode attributes

When using the classic page/post editor, several attributes can be passed to the [fen]...[/fen] shortcode to customize how the corresponding chess diagram is generated. These attributes are presented below.

To be noticed: these attributes correspond to the customization settings proposed in the right panel of the Chess diagram block for those using the Gutenberg page/post editor. The customization features proposed by RPB Chessboard are the same whichever the page/post editor you are using.
