This update adds support for:
- Unicode 16 Large Type Pieces (they are really cool, you *have* to see
them)
- Unicode 13 Sextants (U+1FB00 - U+1FB3B)
- Octants, sedecimants, eights, miscellanrous blocks, separated
quadrants and sextants, and diagonals
- Segmented digits (think LED numbers)
- Checkerboards
It also fixes the coordinate system used in all of the blocks,
half-blocks, quadrants and eights for consistency.
This update does **not** include the new "Nerd Fonts" variant of
Cascadia Code or Cascadia Mono.
With big thanks to @PhMajerus for contributing all of the new symbols
for legacy computing.
