add blast-db

[chiras]

maybe also add a blastdb

e.g.:

makeblastdb -in COI.Diptera.BavariaGenera.2019-02-15.tax.fa -parse_seqids -blastdb_version 5 -title "COI.Diptera.BavariaGenera.2019-02-15" -dbtype nucl

zipped maybe, as they contain multiple files?

Sure, we can automatically perform this task and include the resulting files in the output.
