 Normalising the occupancies reported by the authors by dividing them by the
 atom site symmetry multiplicities.

 Antanas Vaitkus,
 2018-07-04

 Adding atomic coordinates, atomic displacement parameter values, space group
 information, R-factor values and other additional information after consulting
 the original publication. It should be noted that some of the occupancy values
 reported by the authors exceed 1; these occupancies were most likely calculated
 by multiplying the site occupancy by the site symmetry multiplicity. The
 aforementioned occupancies were purposely not modified in this revision
 and will be changed in a separate commit.
