Add fuzzer for (A)PNG decoder
Implement a fuzzer for the PNG decoder. It uses three animated png images
created by joostouwerling@google.com and three existing static PNG images
in WebKits LayoutTest resources as a seed corpus.
It works for both the current PNGImageDecoder, which only supports
decoding static PNGs, and the new PNGImageDecoder which also supports
decoding animated PNGs. This is achieved by having both static and
animated PNG images in the seed corpus.
