Fix reading of image alpha channel (bug #32986). * __magick_read__.cc (read_images): fix reading of the alpha channel by using separate index for alpha channel (regression from cset dcac71776ae8); make use of Magick's MaxRGB constant; change inversion of alpha channel to avoid use of abs(); (read_indexed_images): remove use of abs () for inversion of alpha channel.
