The PNG header is wrong in a way that png files can be found, but carving produces output that needs repair before viewing.
The PNG footer is just completely wrong.

Fix both by using the correct PNG signature as header and the full IEND chunk as footer.

@bcarrier @esaunders Could this please be pulled?

I wasted some time on this, fixed it myself then realized there's an already existing PR for it.

I didn't test it, but it looks correct.
