Fix resolution field in mmcif_parsing

Without the break statement this function will fall back to setting the resolution to _reflns.d_resolution_high for most structures, which reflects the resolution limit in the raw data and not the final structure (see https://mmcif.wwpdb.org/dictionaries/mmcif_pdbx_v50.dic/Items/_reflns.d_resolution_high.html and https://mmcif.wwpdb.org/dictionaries/mmcif_pdbx_v50.dic/Items/_refine.ls_d_res_high.html).
