[morx] Implement forward/backward processing
...
We reverse too many times. Can be optimized. But I doubt many fonts
use reverse lookups, so doesn't matter.
Other than not applying user features, this completes morx table
implementation.

Disallow null-enabled offsets to unsized structures...
...
...like UnsizedArrayOf<>.
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,
because it's nost safe to use our fixed-size null pool for types that have
their size external. So, use non_null'able offsets for these.
A further enhancement would be to make use of min_size in Null<> itself.
Will try that after.

[dfont] Solve the mystery +2 offset thing!
...
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.
This, concludes my dfont hacking. The code looks great now, and I'm happy to leave it.
Fuzzers might disagree though, we will see!
