Makes some of the errors a bit less descriptive. But this is pretty stable by now and the errors fire basically never, so that seems ok. Needing the explicit `AK::` prefix is a bit awkward, but that'll go away once this class moves out of LibPDF. Move error() into the two subclasses. I'll remove it from CFF in a follow-up. No real behavior change.
