I'm having issues with getting this pipeline working on Seqera Platform with the Fusion filesystem, and because this module has such huge requirements, I think what we may need to do in the future is add this as a proper subworkflow, copying from the Dockerfile, running each of these workflows separately:

https://gitlab.ebi.ac.uk/uniprot-public/unifire/-/blob/master/docker/scripts/download-interproscan.sh?ref_type=heads
https://gitlab.ebi.ac.uk/uniprot-public/unifire/-/blob/master/docker/scripts/download-unifire.sh?ref_type=heads
https://gitlab.ebi.ac.uk/uniprot-public/unifire/-/blob/master/docker/scripts/update-taxonomy-cache.sh?ref_type=heads, which calls https://gitlab.ebi.ac.uk/uniprot-public/unifire/-/blob/master/docker/scripts/update-taxonomy-cache.py?ref_type=heads
and finally, separate out each of these: https://gitlab.ebi.ac.uk/uniprot-public/unifire/-/blob/master/docker/scripts/unifire-workflow.sh?ref_type=heads
