Override global `dataset_info` properties when processing CrossDock using only Ca atoms

[amorehead]

• Now overriding global dataset_info properties when processing CrossDock using only Ca atoms, as otherwise these values would not be updated (i.e., correct) e.g., for amino_acid_dict at runtime.
• To my best knowledge, without this change, it is currently not possible to process CrossDock with ca_only=True.
