03f76b73b4 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.

see https://github.com/libvips/libvips/issues/2192

9246094033 Fix function pointer cast issues 
It is undefined behavior in C and C++ to cast a function pointer
to another type and call it that way. This does work in most native
platforms, however, despite it being UB, but in WASM it can fail.

a2d196b736 add subifd support to the TIFF writer 
A new subifd switch enables the writing of pyramids layers into subifds
(rather than the default successive pages). This switch is enabled
automatically for multi-page pyramids.
