ENH: Add parent lineages as partiallyAliased column for recombinants

[corneliusroemer]

Would be great to add recombinant parent info to the partiallyAliased column in SC2 datasets

In addition, it would be good to have the full aliased name in the tooltip so as to make it possible to see what long names mean

Also, it would be nice to add full hierarchy of aliases in the tooltips to allow learning them without looking up - shouldn't be hard:

B.1.1.529.5.3.1.1.1.1.2
BA.5.3.1.1.1.1.2
BQ.1.1.1.2
DN.2

Should be implementable with nextstrain/nextclade#985, which allows to display secondary clade-like node attrs in the tooltip.

Right now the values accepted are strings. That is 1 key (a string) corresponds to 1 value (a string). There might be a way to also assign lists if needed. Otherwise a workaround is to have a comma-separated list in a string.
