add "premultiply" param to tiffsave
...
Some programs, like indesign, only work with premultiplied alpha in TIFF. To
make TIFFs which are compatible with these programs, we'll need an extra
TIFF save flag (perhaps premultiply?) to premultiply alpha and save as
EXTRASAMPLE_ASSOCALPHA.

revise unpremultiply, again

We were not detecting division by zero carefully enough, nor clipping
the alpha range sufficiently in unpremultiply.

better 8/16 bit casting for pngsave
...
pngsave was just using the image format to decide whether to save as 8
or 16 bit PNG. With this patch it checks Type as well.
This means that eg. a uint32 image tagged as sRGB will save as png8, but
a uint32 image tagged as RGB16 will save as png16.
