Update wcslib to latest version

I got a failure trying for 4.14:
curl: (78) RETR response: 550
Error: Download failed: ftp://ftp.atnf.csiro.au/pub/software/wcslib/wcslib-4.14.tar.bz2
wcslib: PGSBOX (plotting) & fortran & cfitsio

- Fortran wrappers (--with-fortran)
- PGSBOX plotting with pgplot (needs X11)
- CFITSIO lib dependency build and linked
- Option to do `make check`
