much faster ismagick
...
We used to Ping files to see if IM would load them, but this can be
extremely slow for file formats like ARW.
Instead, use GetImageMagick() ... it just checks the magic number.

istiff tests first dir rather than magic number
...
We were testing for TIFF by checking the magic number at the head of the
file. However, formats like ARW are TIFF-like without being TIFF, and
will not load with tiffload.
Instead, try reading the whole of the first directory. This is enough to
stop tiffload trying to load files where it will simply fail
immediately, and make libvips fall back to eg. imagemagick.

revise page-height rules again
...
Only set `page-height` if `n` is set as an argument. This means you only
get a multi-page image if you specifically ask for it.

more consistent behaviour for multi-page load
...
Some loaders were setting page-height even when the user was loading a
single page triggering unexpected multi-page behaviour from later
savers.
New rule: only set page-height when loading more than one page.

better compat with older libheif
...
We were looking for "yes" from the builtin_h265_decoder variable to
enable heifload, but this variable was only added in libheif 1.3, so we
failed to turn on heifload correctly.
We now look for not "no", ie. default on.

better pdfload page size rounding
...
We were doing simple round down for page size with @scale param. But
this makes it very sensitive to rounding errors, so do rint() instead.
vips-resize() does rint() on the output size as well for the same
reason.
