Update DIAMOND_analysis_counter.py with if/else for multiple brackets…

… in annotations

Thanks to Menia Gavriilidou for this suggestion!  

In the DIAMOND_analysis_counter.py script, there's now logic to account for if a RefSeq annotation description includes multiple sets of square brackets `[]`.  Not guaranteed, but better than dropping the line.
