Setrixtui is a Setris/Sandtrix-style game in the terminal. Place
coloured blocks; when they lock, they turn into sand.

Clear lines by making a single colour connect the left edge to the
right edge (8-neighbour, path can be diagonal).

Matching piece colours and completing those spans scores points;
remaining sand falls under gravity.
