[sanitize/Coverage] Keep a map of sane coverages
Fonts like Gulzar reuse the same coverage over a thousand times
sometimes.
However, this doesn't speed up sanitize unfortunately. Looks
like calling Coverage::sanitize() is already very fast. We're
just doing A LOT of it.
The map slowed it down in fact. A set was even slower.
Going to revert.
