This fixes a class of crasher bugs, mostly with color and AAT tables. We
cannot use nullable offsets to varsized data that does not declare min_size,

their size external. So, use non_null'able offsets for these.

Previously, ResourceForkHeader was defined as 30 bytes, having the typeCountM1 as last member.
There was a mysterious offset-by-2 in the code, derived from FontTools and JDK code this was
ported from.
In testing, I observed that typeListZ offset is actually 28. Suggesting that the typeCountM1
does NOT actually belong to ResourceForkHeader, but belongs to the array itself. Adjusting for
that resolves the mystery +2 offset hack, so everything is clean and good now.
