Change default levels of taxonomic ranks classified

Hi @syrenawhitner,

You can use as many taxonomic ranks as you'd like. As long as the ranks are delimited by a ;, and have the same number of ranks for each taxa, you'll be fine.

For example, you can use RESCRIPt to make a SILVA or GenBank databases with 5 ranks, 9 ranks, 14 ranks, etc...
