With version 7.6, WCSLIB has recently added the wcspcx() function to split CDi_j matrix when it won't interfere with the distortion.

It is still relatively recent (released on April 2021), so many users will probably not have it yet. But in a year or so, most users should have it, for us to assume it in Gnuastro. We can add a configure-time check for it and use it where necessary.
