Different taxonomy level aggregration and extracting full taxonomic classification.

[microb123]

I tried to aggregate the taxa using the argument "tax_level" from ANCOMBC but other taxonomic levels are included. For instance, when I aggregate taxa at the "genus" level there were couples of the family included. I tried with both tse object and the phyloseq object but the issue is the same. When I tried with "aggregate_taxa" function from the microbiome r package there weren't any families included but it gave a different result.

Also, how can we extract full taxonomic classifications? I tried with tse object as suggested in #147 but it didn't work.
