OBELiX randomized CIFs (321 structures, noise-perturbed from experiment)

The 321 CIF files distributed with OBELiX (NRC-Mila), repackaged for Ouro. These are the authors' public "randomized" structures: crystal structures with random noise added to atomic positions while preserving symmetry, used to avoid leaking the exact experimental structures into benchmarks. Entry ids match the `id` column of the OBELiX dataset table and `cif_id` in the filename. License: CC-BY-4.0 (NRC-Mila/OBELiX). Source: github.com/NRC-Mila/OBELiX
