Wrapper to go through project datasets and do revalidation in one-stop-shop manner.
This works best when datasets are directly under "Raw Data" (the standard and most-preferred organization)
or at most one additional level of nesting. See https://help.nf.synapse.org/NFdocs/how-to-organize-data.
For selective validation or more complicated structures,
look at meta_qc_dataset to do manual or interactive dataset-by-dataset validation.
