This makes the extraction comparison more readable (using ints instead of floating point format), fixes a but or two, and also includes the a compiled and executed test of the comparison library.

@hiker Just some minor comments, I like the new extraction stats table, it's easier to quickly see if there is important differences imo.

[hiker]

Looks like I forgot to mark this as ready. I've brought it up to latest master, and triggered the CI (which should not really be affected by the changes here).

@hiker All comments have been addressed, this is ready to merge if the integration tests come green.

@hiker Unfortunately the libraries compilation failed with:

./test_compare | grep "a_dbl    *15 *1 *2 *3 *4 *5" > /dev/null
At line 147 of file compare_variables_mod.F90 (unit = 6, file = 'stdout')
Fortran runtime error: Missing comma between descriptors
(A8' ',6(I12, ' '),4(E12.7,' '))

Which compiler (and version) is that? I've tried nvfortran (23.5), gfortran (11.4), ifort (2021.8.0), and ifx(2023.0.0), and they are all working fine.

Ah, found it - gfortran 15. As far as I can see, I don't have access to that atm :( I'll see if I can figure out what is happening.

[hiker]

I think I got it. I'll trigger the full CI tomorrow.

[hiker]

I've fixed the conflict in the changelog, I don't think there's a need to rerun the CI because of this.

Thanks @hiker, this ca be merged now
