PEImageReader is documented as logging something if Initialize() fails, so this
isn’t strictly necessary unless you think there will be lots of entry points to
PEImageReader::Initialize and it’ll be important to pinpoint this one.

Done.

Like Timestamp(), you can implement Address() and Size() easily with what you
have now. The PEImageReader already stores both of them.
