* Add new error types and descriptions. * Do not crash on missing 0x100 and 0x300 PUP file entries. * Report an error on missing PUP package inner files. * Fix overflow in file-size against header check. * Move all header errors to pup_object class. * Move verbose error descriptions to pup_object class. * Minor optimizations.
