Add alignment summary: organisms

[njrollins]

Would be useful to give quick visual summary of what organisms are collected in the alignment.

One option: represent aligned sequences in a tree or simply a bar-chart, colored by species membership
e.g. by

• fetch NCBI taxonomy from UniProt IDs (batch query API) or TaxID in annotations.csv
• input IDs to visualize as e.g. tree (https://itol.embl.de/)
• Perhaps color at according to chordata + mammalia + domain (other eukaryotes, bacteria, virus, ..)

Could in the future be nice to do something similar, but color branches by strongest Pfam hit to each seq overlapping aligned region

was working on this with the alignments I've been reviewing, and think I found something that might be nice with the hierarchical data one can pull from NCBI.
I pulled taxa information using TaxID in *_annotations.csv, then used plotly for the visualization, grouping on superkingdom, phylum, and order (could try using class, or family, but I chose some higher ranks to keep graph light). plotly also makes its charts interactive, so you can view totals or subset to different groups. The sizing of the lettering is also a bit noisy, but there are ways of setting those to be fixed. can share my notebook/start a pull request if this seems like a suitable addition!
