inputs/REMIB/Specimen/: translated single-column filters to postprocessing derived columns, using the steps at wiki.vegpath.org/Switching_to_new-style_import#stage-I-source-specific > "translate single-column filters to postprocessing derived columns". null-mapping filters now use wrappers around new util.map_nulls(). note that the verbatim columns input to the filters need to be renamed to avoid name collisions with their filtered columns, which must be VegCore terms for new-style import.
