input.Makefile: Maps validation: $(newTerms): For simplicity, subset the columns before running filter_out_ci

mappings/: Removed no longer used Veg+-VegBIEN.csv and derived autogen Veg+.self.csv

input.Makefile: Maps building: %/unmapped_terms.csv: Use $(coreMap) instead of $(vocab) because the terms should already be translated to VegCore terms, rather than still being Veg+

input.Makefile: Maps validation: $(newTerms): Fixed bug where header needed to be removed before running filter_out_ci because filter_out_ci only removes the header if it matches the vocabulary's header. Removing the header afterward can cause the first row to be removed instead if the header was already removed.

cols: Support CSVs without a header, such as intermediates that become unmapped_terms.csv, new_terms.csv

inputs/: Regenerated unmapped_terms.csv, new_terms.csv

input.Makefile: %/.map.csv.last_cleanup: Removed no longer used prerequisite $(vocab)

input.Makefile: %/.map.csv.last_cleanup: Canonicalize separately on $(coreMap) and $(dict), instead of requiring them to be combined in $(vocab)

input.Makefile: Use mappings/VegCore-VegBIEN.csv instead of mappings/Veg+-VegBIEN.csv as the core map, because the automapper now takes care of Veg+ -> VegCore translation

inputs/*/*/map.csv: Moved filter suffixes to separate filter column to enable automapping to work on those mappings' terms, using the steps at <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/Map_refactoring#Move-filter-suffixes-to-separate-filter-column&gt;. Note that the only changes to VegBIEN.csvs are the (now automapped) names of terms in "No join mapping" comments.
