When we run any Gnuastro program on raw HST images, we get WCSLIB errors and
the WCS is not loaded:
$ wget -Oj9en0pnaq_flc.fits
'https://mast.stsci.edu/api/v0.1/Download/file?uri=mast:HST/product/j9en0pnaq_flc.fits'
$ astarithmetic j9en0pnaq_flc.fits

This was originally reported by Alex Borlaff in a post to bug-gnuastro
<https://lists.gnu.org/archive/html/bug-gnuastro/2023-01/msg00008.html>. As
mentioned in later messages of that mail series, we should confirm which one
of these scenarios (or maybe anther scenario) is causing this problem:
* it is a problem in the way we use WCSLIB in Gnuastro.
* it is a non-standard usage of WCS keywords in the HST pipeline.
* it a bug in WCSLIB.
