 Updating space group information and adding the symmetry operation list.

 Antanas Vaitkus,
 2018-06-17

The following automatic conversions were performed:

'_chemical_melting_point' value '369-371' was changed to '370.0(10)'
- the average value was taken and precision was
estimated.

'_atom_site_thermal_displace_type' tag value 'Uij' was
replaced with 'Uani' value 17 times.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w = 1/[\s^2^(F) +
0.000225F^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) + 0.000225F^2^]'.
