In order to make interactive QA plots such as
DM-11682, we need to persist parquet files containing the compiled data that are used to make the static matplotlib plots. Admittedly, this should be a temporary step until all the source info is easily loadable from a column-store database, but for now it is necessary. At the visit level it might be less so, but I'll do it anyway. This is probably technically part of DM-10859, but I thought it might be useful to get it in its own ticket so it can be merged quickly.
