belongs-to-lineage awkward structure

[jcbarret]

Currently each belongs-to-lineage section is a list of dictionaries with one key:value pair in each. For instance, carnival-shimmy looks like: [{'PANGO': 'B.1.351'}, {'nextstrain': 'N501Y.V2'}], whereas I think it's more natural to have it as a single dictionary, a la {'PANGO': 'B.1.351', 'nextstrain': 'N501Y.V2'}. This can be achieved by replacing the - with a space before each key (PANGO, nextstrain, etc).

This sounds like a sensible change that we will target for a future release. Thanks!
