qoi-fu doesn't work correctly for encoding 4 channels images

[wx257osn2]

Current qoi-fu works not same as reference QOI implementation only if encoding 4 channels images.
The size of output by qoi-fu is bigger than one by reference.

Please see more information on my test repo.

Thank you very much for reporting this!
It was a suboptimal compression which affected some images, regardless of the alpha channel.
I will make a binary release in a week or so.
