Enhancement: add whitelist to pre-processing

[beardymcjohnface]

Hi,
This is an interesting suggestion. Do you think having an option to use a custom primary database for the viruses of interest would work? The primary searches do essentially what you're suggesting, but for all viruses, and the secondary multi-kingdom searches weed out the false positives from this reduced pool of sequences.

Yep, absolutely. Depending on how much database prep is needed for the primary database, I could envision situations where providing a FASTA whitelist file would be simpler and wouldn't require modifying the virus database. If the primary database is already just a FASTA file of all viruses, then specifying a custom FASTA file of, say, all human viruses would be great.
