 Updating space group information and adding the symmetry operation list.

 Antanas Vaitkus,
 2018-06-14

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w = 1/[\s^2^(F) +
0.005F^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) + 0.005F^2^]'.
