The scheme used in draw_sextant works well enough, but the
feed was broken. 21 and 42 need to be skipped, not 20 and
40. Without this change, the following glyphs are broken:
U+1FB13 BLOCK SEXTANT-35 馃瑩 renders as LEFT HALF
U+1FB26 BLOCK SEXTANT-46 馃 renders as SEXTANT-146
U+1FB27 BLOCK SEXTANT-146 馃 renders as RIGHT HALF
With this change, the entirety of the sextant block works
correctly. Found debugging the Notcurses sextant blitter:

Closes #3106
