d971c75d6f block 0 width or height images from imagemagick

ff450497ff add read loops to heif and ppm as well 
We were not looping on vips_source_read() in these loaders, so they
could fail when reading from very slow pipes.

6894159ad5 fix icc-profiles and dzsave --no-strip 
We were not copying metadata down pyramid layers in dzsave, so
--no-strip didn't allow icc profiles on tiles.

91d9610a55 fix out of bounds read in tiffload 
libtiff can change the value of some fields while scanning a corrupt
TIFF file and this could trigger an out of bounds read.

This patch makes tiffload more cautious about rescanning a TIFF
directory before reading out header fields.

fc1e609f44 libheif: expose speed parameter (currently AV1 compression only) 
Supports both aom and rav1e encoders by limiting to a 0-8 range.

(The rav1e encoder accepts speed values of 9 and 10 but these
use 64x64 blocks more suited to video than images.)
