b836749b75 close jpeg read early 
The current behaviour (close input handles on unref) works for languages
like C / C++ / Python / Rust / etc. where things get unreffed automatically
when they go out of scope.

On languages like Ruby / C# / node / etc. where things are unreffed on GC,
files can stay open for a long time after you've finished with them. This
interacts in an unfortunate way with the Windows default of refusing to
remove open files.

This change closes file handles as soon as the scan of the input file
finishes, and therefore produces something closer to expected behaviour
for GCd languages on Windows.

d48f80130b switch to g_open()/g_fopen() 
Might help with files being left open, perhaps. It's certainly neater.

26fcccba9b fix out of bounds write in radiance 
It was using a fixed 64-byte stack buffer for the RHS of format lines.
Lines can be MAXLINE (2048) chars, so a long line could overflow. If we
use MAXLINE for the small buffer as well, we are guaranteed to not
overflow.

06a40cc7ee sort-of works 
but can't set meta correctly, try:

	$ vipsheader -a sub-CC00050XX01_ses-7201_T2w.nii.gz

see all fields, but

	$ vips copy sub-CC00050XX01_ses-7201_T2w.nii.gz x.v
	$ vipsheader -a x.v

only see a few, odd

d06c2fee22 use exif_tag_get_name_in_ifd() everywhere 
exif tag names change with the ids they appear in, so you must always
use exif_tag_get_name_in_ifd(), not exif_tag_get_name()
