redFiveIndexesfunction
WHICH TILES OF A LIST ARE THE RED FIVES. A set holds one red five of each suit, drawn in place of one of its four fives, and a face's letter cannot say which, so the first five of each suit in the list (in the layout's slot order, or the hand's) is the red one. A pure function of the tiles, so the same tiles are red every time.
