Create ctas input from SDTM LB domain
Input_Labs.RdProduces range-normalized lab timeseries and ratio-missing timeseries for
each lab test. Both share the same parameter_category_2 (the LBTESTCD)
so they are grouped together in the app sidebar and plotted in the same
faceted panel. Timepoint ranks are recalculated and unscheduled visits
are filtered out.
