Title: Fixed issue with RDP classifier's dereplication of taxa

Fixed issue when the id-to-taxonomy map has duplicate *case-insensitive* taxon names at the same depth.

The RDP classifier internally performs a case-insensitive check for duplicate taxon names at a given rank, and thus would throw an error when it hit this case.

This issue recently arose when testing out a new fungal database with the RDP classifier.

@kylebittinger, I'm especially interested in your feedback regarding this fix, as you're most familiar with the RDP classifier code.
