Rebuild: rules:signatures, and voyager 1's 29 learned garbage signatures

rules:signatures publishes a rule set version whose dropped signatures
come from a file of tool<TAB>group lines (--add to add to the current
ones). database/data/voyager1_signatures.tsv: voyager 1's dropped ones
(>=100 probes, <=0.5% named), with their probe counts; the two builds
name the posting tools the same way.
