decodePNG: The picoPNG function, decodes a PNG file buffer in memory, into a raw pixel buffer.
out_image: output parameter, this will contain the raw pixels after decoding.
  By default the output is 32-bit RGBA color.
  The std::vector is automatically resized to the correct size.
image_width: output_parameter, this will contain the width of the image in pixels.
image_height: output_parameter, this will contain the height of the image in pixels.
in_png: pointer to the buffer of the PNG file in memory. To get it from a file on
  disk, load it and store it in a memory buffer yourself first.
in_size: size of the input PNG file in bytes.
return: 0 if success, not 0 if some error occured.
