Expand description

Add an annotation reference to a page’s /Annots array.

Handles both inline arrays and indirect (referenced) arrays. When the indirect Annots array cannot be resolved (e.g. it lives in a compressed ObjStm that lopdf failed to expand), falls back to replacing the /Annots entry with a new inline array so the annotation is never silently dropped.
