(Do not merge until validation recalculation) Use mmCIF validation reports instead of XML

[aliciaaevans]

Once validation recalculation is done, every entry will have an mmCIF validation report. ThetoCifWrapper marshal helper and internal validation dictionary will no longer be needed. Instead, the CIF can be merged with the structure's mmCIF.

Note: the testLocalRepoUtils tests won't pass until after the recalculation because it's expecting a certain number of categories, including vrpt, to be found. Also, the validation cif files need to be added to the mock-data repo.
