decode(): ImageData should match input format

First of all, thanks for this fantastic little library! I'm using it for reading 16 bit rgb images and noticed that the decoded data always contains 4 channels (rgba). This makes it very difficult to continue processing the image data in my workflow.

I therefore suggest that the decoded data format matches that specified by the colorType. So for colorType = 1, the format should be [b0, b1, b2...], for colorType = 2 it should be [r0, g0, b0, r1, g1, b1...], etc.

This could also be made a parameter to the decode() function.
