schemas/vegbien.sql: place.geovalid: require it to be NOT NULL so that it's always a 2-valued boolean (but default it to false since it's not a required field)

mappings/VegCore-VegBIEN.csv: place.geovalid: use false instead of NULL

inputs/GBIF/raw_occurrence_record/run: table.tsv/make(): exclude deleted rows (i.e. where the deleted timestamp is non-NULL)

inputs/GBIF/raw_occurrence_record/header.csv: regenerated using ./run. since the table is reimported as a CSV, it uses bin/csv2db, which prepends an additional row_num column.

inputs/GBIF/raw_occurrence_record/run: table.tsv/make(): remove explicit cols list to include all cols. the file size of the generated table.tsv will increase by ~3x, but should remain reasonably-sized compared to our available disk space.

bugfix: inputs/GBIF/raw_occurrence_record/run: table.tsv/make(): need \ line continuation after vars so they only apply to the command rather than being set as global vars

bugfix: lib/runscripts/table.run: load_data(): use new $verbosity_min instead of running `verbosity_min` so that the command name logging is not output with the new verbosity

lib/sh/util.sh: added $verbosity_min to set a `verbosity_min` value after the command name, etc. has been logged, so that the logging itself is not output with the new verbosity

schemas/vegbien.sql: range_modeling_input: include only plants (i.e. rows with higher_plant_group IS NOT NULL)

schemas/vegbien.sql: range_modeling_input: added higher_plant_group, for use in restricting rows to plants
