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.
