CwannXML test still does not work. But the results are very near to the target.

...still buggy and very incomplete.

The new test does not pass yet but it might already work.

Two changes:

1. Specify Wannier90 1.2 in the wann_inp file.
2. Adapt some array copy to the actual dimensions. ...this was a problem in the debug version.

get wann_setup interface working for wannier 1.1/2 and 2.0 with wan90version input in the most brutal way by copying the wann_postproc_setup again and adjusting the interface

add old commit from frank treating problem:  Included lmax into the argument lists of wann_mmk0_sph.f and wann_mmk0_updown_sph.f. Use lmax(n) instead of lmaxd to restrict angular momentum summations. Without this bugfix sometimes NAN pops up in the rspauli.1 file if there is more than one atom type in the unit cell and the lmax of the various atom types are different

get updown working with updated wann_mmk0_updown_sph file from frank and avoiding some double allocations

fleur.F90 wannier call should put l_real=.false. also if l_soc is true; wannier.F allocations of zmat*%z_* should only be done one<- bug due to 110 spin loop

Also in this commit: Some minor changes to error messages and some additional
array allocations in wannier/wannier.F.

As some parts of the Wannier code rely on JPHs modified Wannier90 libraries
wannier4.a and wannier5.a I now differentiate between them and the official
version. wannier4.a and wannier5.a are only needed for certain code parts.

It looks like we are reaching testing/debugging phase.

Note: There is still some additional work required in fleur.F and maybe also
in other files.

In this commit there mainly are some adaptions to the new eigenvector I/O.

Note: The Wannier code is not yet connected to the main code

It is needed for the Wannier code.

This is needed for the Wannier code and for GW.

...I now reached linker error phase.
