Required by astropy v6.0

- Update to 8.2.2
  * In prj.c, a number of variables with global scope that are only
    used internally were declared static to avoid namespace
    conflicts arising in Link Time Optimization (LTO) builds of the
    Rwcs wrappers.  This is a patch release as it does not affect
    the library itself other than in localising some symbols that
    were never meant to be global. Reported by Rodrigo Carrizo with
    patch.
    Likewise for an internally used helper function, prjoff().
    Likewise for a handful of variables in cel.c, dis.c, lin.c,
    tab.c, wcs.c, wcsfix.c, and wcshdr.c.
- WCSLIB version 8.2
  * In wcshdo(), fixed character buffer overflows in the comment
    string for the longitude and latitude axes triggered by some
    projections, and also the formatting for generic coordinate
    systems.  Reported by Shu Niu.
- WCSLIB version 8.1
  * Changes in the contents of the auxprm struct (in 8.0 beta)
    necessitated incrementing the major version number from 7 to 8,
    i.e. the ABI changed. Took the opportunity for minor tweaks to
    wcsprm and disprm.
  ## C library
  * In disprm, changed the order of maxdis and totdis to ensure
      correct alignment of doubles on 32-bit machines.
  ## Fortran wrappers
  * Match changes to disprm in the C library.
  * In the Fortran test suite, inserted a brief pause between plots
    in tprj2, tspc, and tpih2, which have long been a blur.
  ## PGSBOX
  * Quell innocuous compiler warnings from gfortran 12.1.0.
