#6060 contained a commit entitled "Allow getpalette() to return less than 256 colors"

This meant that there were fewer bytes when saving in IM.

fp.write(im.im.getpalette("RGB", "RGB;L")) # 768 bytes

But IM still expected 768 bytes when reading.

palette = self.fp.read(768)

So this PR pads the palette to 768 bytes when saving.
