The LCA methods will leave blank taxonomies if there is no LCA (e.g., because one is "Unclassified").
Should instead fill in a placeholder label (e.g., 'Unassigned'), as blank labels can cause some downstream methods to break. This placeholder label string should be exposed as a parameter so that users can specify placeholder labels that match their pre-existing taxonomies.
