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.
thanks HongxuChen

fix a tiff2vips crash on fractional samples

tiff2vips failed if samples_per_pixel was not a multiple of 8, ie.
byte-aligned, and the image was not palette-ised

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

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()

Add 8bpp PNG quantization support

This adds support for saving 8-Bit one band palette based PNG images
with palette based alpha channel (often called PNG8+Alpha).
The image is first converted to sRGBA and then quantized using
libimagequant controlled by the colors, Q and dither params.
