game: Add Barrier cell type
Barrier cells are cells that never change and are not affected by rules
(hardcoded behavior in the Rule class). Barriers can be used by boards
to shape their board, e.g.
// `#` for barriers, `.` for empty, `a` for team A, and `b` for
// team B.
const board = [ "####################",
"####...######...####",
"###aa....##..b...###",
"##a....a...bb.....##",
"###....aabbbb....###",
"#####...a.bb...#####",
"########a...########",
"#########..#########",
"####################" ]; // 20x9 heart shaped
As illustrated, boards stay list of strings, but thanks to the barrier,
they can adopt specific shapes. A regular array shaped board unifies
the API between downstream users and our internal states.
