Added _atom_site_type_symbol to
the atoms loop to complete the structure as from the reference

#----------------------------------------------------------------------

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value '1/[\s^2^(F)+0.00063F^2^]' was
changed to 'calc'. New tag '_refine_ls_weighting_details' was
created. The value of the new tag was set to 'w =
1/[\s^2^(F)+0.00063F^2^]'.
