taxa-barplot: set 'others' group when plotting taxa

[lizgehret]

After assigning taxa when making the associated bar plot, it would be nice to have the ability to set an "others" group. For example, for taxa that are lower than 1%, group all of them to something like "others" or "low-abundance".

OP from the QIIME 2 forum: https://forum.qiime2.org/t/how-to-set-others-while-assign-taxa/23196

Is this a feature request for q2-taxa, or for q2-feature-classifier (or both, or neither)? Taxonomic assignment happens with the various methods in q2-feature-classifier. I could certainly see having some sort of toggle-able widget in the barplot visualization that would allow for on-the-fly regrouping of low abundance features, but I think there's also precedent for addressing this kind of thing using standard filtering techniques, like:

@thermokarst this is a feature request for q2-taxa when creating the barplot viz - the toggle-able widget that you mentioned sounds like what the OP was asking about (forum post linked above - although their question is somewhat vague).

Can you edit the title and issue body to clarify that? The "assigning taxa" parts are why I asked for clarification. Thanks!

@thermokarst can do, sorry for the confusion!
