Since the upstream packaged grammar now recognizes LAN moves, we add support for them here, treating them identically to SAN moves in every regard, including faces.
Bug: the grammar does not yet support LAN moves within variations, which is already fixed upstream but not propagated to the Emacs package.
Many LAN-style moves will still be denoted as san_move in the CST, but LAN captures will always be denoted as lan_move. This should not cause any issues visible to the user, since the two are always treated the same in the code.
