Changes (Release 4.15.0)

Summary (pypdfium2)

• In helpers, closing a parent object now automatically closes the children to ensure correct order. This notably enhances safety of closing and absorbs the common mistake of closing a parent but missing child close calls. See commit eb07605 for more info.
• In init_forms(), attempt to call FPDF_LoadXFA() and warn on failure, though as of this writing it always fails. An upstream issue is suspected.
