Unboxing refers to the process of both unmerging a column, either a label or a strip, while also separating rowwise by the `sep` argument. It is meant to isolate the Concept attributes from a merge column while also taking in account that rowwise aggregates may have also occurred, and without separating these values out, some concepts in the source data may be misparsed.
unbox_label(data, label_col, sep = "\n", remove = FALSE)
