Get study table with most recent metadata files

The table will have all documentation files, but will only keep the most recent version of files for the following metadata types: biospecimen, manifest, assay, individual. Assumes that the fileview is for a single study, but ultimately will keep most recent file information for each metadata type, without filtering by study. If want to also filter by a study name, specify name in `study_name` parameter.
