make out of order read a fatal error
...
For png and jpg, out of order must always be a fatal error, since you
can't read from a specific y position.
This was a g_assert() before which meant that this test was missing from
production builds. It's now always a fatal error.

All operations are now slightly smaller and simpler.

note and use res unit on jpg load/save
...
previously, jpeg save always used pixels/inch and jpeg load converted to
vips pixels/mm
now on jpg load the image's res unit is recorded in
VIPS_META_RESOLUTION_UNIT, and on jpg save the res unit is set from
VIPS_META_RESOLUTION_UNIT (or defaults to inches).
you can now copy a cm-preferring tiff to a jpg and the unit is preserved
