look into mmseqs2 for validation and maybe addition

[ctb]

riffing off of conterminator, martin steinegger suggested that we look at using mmseqs2:

We have a method in MMseqs2 to predict a consensus taxonomical label for a
contig by considering all ORFs that match to homologous sequences in a reference database.
