latin: domino tile formatting and encoding

Another efficient set containing (7*8/2=) 28 distinct options as listed on
<https://en.wikipedia.org/wiki/Dominoes?oldid=1037160475#Tiles_and_suits>,
applied alphabetically in increasing weight.

Could also be used to display existing tap codes in single glyphs, but
probably shouldn't.
