Hello I also have the same bug as Attempt to read from field 'int[] net.ellerton.japng.argb8888.Argb8888Palette.argbArray' on a null object reference

@vicktorial Can you please outline steps to reproduce, including a specific PNG file if you have one.

I'll be integrating contributed patches soon - I'm a bit behind at the moment.
