0c7b65e156 allow both dpi and scale to be set for pdfload 
pdfload didn't allow both dpi and scale to be set. This patch makes the
two settings combine if both are given.

2403b29c1f 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.)

348e5e1523 don't set JFIF res if we will set EXIF res 
Some JPEG loaders give priority to JFIF resolution over EXIF resolution
tags. This patch makes libvips not write the JFIF res tags if it will be
writing the EXIF res tags.

801111a2fa better dint rules 
We had some special cases coded for dhint inheritance, but they could

predictable.

6b2079bfd3 update magick metadata naming 
IM seem to have changed their rules for naming metadata chunks. They are
now lowercase and ICM is renamed to ICC. Add a simple test too.
