are 32bit RGBA images supposed to work?

I don't think I understand the code here for the case (seemingly common, I would think) of a 32bit RGBA input image:

pyramidio/pyramidio/src/main/java/gov/nist/isg/pyramidio/tools/ImageResizingHelper.java

Line 49 in 1d5c802

return resize32bppImage(img, width, height);

The resize32bbpImage() method seems to be hardcoded to assume that there is only one channel, not 4.

In practice this seems to be a bug, when using a 32bit RGBA input image we get wrong outputs.

From what I remember, I developed this function for 32bpp grayscale images indeed.
