Implement PixelRegion option for imread().
* imread.m: document new option.
* private/__imread__.m: parse new option and set defaults.
* __magick_read__.cc (calculate region): new option to calculate the region
to be read, shifts in memory required, and output image size.
(read_indexed_images, read_images): implement reading of only specific
regions of an image.
(__magick_read__): get octave_scalar_map at start for simplicity.
