support very large images #118

Seashore in version 2.5.7 has a limit of 16k width/height images, which in RGBA8888 is about 1GB.

Supporting larger images requires a review of all int/long variable usage, and requires updating the file format to support > 2GB file offsets (aka GIMP 2.10 which can only be read at the moment).

as a stop gap, changing the total image size to 2GB, rather than dimensions, is probably a better solution (so width height 4 < 2GB)
