[Wien] state normalization problem violates correct spin expectation value :: modified w2w code

[Martin Gmitra]

Thank you very much for your advice!

I have changed the parameter LMAX2 to 12 (before was 5) in modules.F
which leads to improvement in three orders:

<n, K | n, K> = 0.999999992267
compared to the previous value of 0.999990071859

More hints are very welcome.

Best regards,
Martin
