nsgifload: enforce maximum GIF dimensions of 16383

nsgifload: enforce maximum GIF dimensions of 16383
...
The GIF spec allows dimensions up to 65535 (16-bit unsigned),
but this equates to 17GB/frame.
A common task is to convert animated GIF to animated WebP,
and the latter supports dimensions up to 16383 (14-bit unsigned),
so that seems like a sensible limit and equates to 1GB/frame.
Also makes the error message consistent with other loaders.
