compass comparison in 11 columns of arrows and triangles

Besides existing single/double arrows and black triangles, add samples for
paired, white, black, triangle-headed (also w/bar), sans-serif, light barb
arrows, and white and medium triangles.

Double triangles last and separate because they are commonly interpreted as
double-width and emoji.
