inputs/publishable datasources.xlsx: updated

fix: inputs/SALVIAS/projects/postprocess.sql: remove private data that should not be publicly visible: remove projects that do not have "There are no specific use conditions attached to this dataset"

fix: inputs/SALVIAS/salvias_plots.~.clean_up.sql: Remove private data that should not be publicly visible: also need to remove metadata-only plots

bugfix: inputs/SALVIAS/plotMetadata_/map.csv: things mapped to project_participant: remapped to event__participant because these actually relate to the event, not the project, even though they seem like project-related fields

mappings/VegCore-VegBIEN.csv: event__participant: allow multiple event__participant columns

fix: inputs/SALVIAS/plotMetadata_/map.csv, inputs/Madidi/LocationObservation/map.csv: things mapped to communityID: remapped to communityName, which is what's used in analytical_stem (communityID is for numeric IDs)

bugfix: schemas/vegbien.sql: locationevent__communities(): inner-join to commdetermination instead of left-joining, so that this does not produce community entries (which occur because there is one commclass per locationevent, but only some commclasses will then have a commdetermination)

inputs/SALVIAS/plotMetadata_/create.sql, map.csv: expanded plot_administrator:party_code_party_ and mapped plot_administrator_name to a 2nd project_participant

mappings/VegCore-VegBIEN.csv: project_participant: use [!...] negative lookahead assertion so that multiple project_participant columns will properly map to separate projectcontributor rows

fix: lib/Parser.py: syntax_err(): error message: lightened the shade of gray so the boundary between the strings before and after the error would be clearer
