Original issue's description:
> Add SkPngChunkReader.
>
> This class allows a client of SkCodec to read chunks in the data
> stream that are not recognized by libpng. This is used by Android
> to specify ninepatch data.
>
> Taken from SkImageDecoder::Peeker. Modify the name of the class
> and its method to be more specific to their use. Make
> SkImageDecoder::Peeker a subclass of the new class, to help stage
> the change in Android.
>
> Add a test to verify that it works.
