[FEA] enriching helpers such as prune nodes to edges

[lmeyerov]

Is your feature request related to a problem? Please describe.

When enriching a graph, there's a lot of wrangling, and can lead to funny workaround

ex: if a superset of nodes are used, the nodes become useless singletons

Describe the solution you'd like

g.edges(df1, 's', 'd').nodes(df2, 'n').enrich_nodes(labels_df, 'n').plot() # only enrich for nodes in df2
g.edges(df1, 's', 'd').enrich_nodes(labels_df).plot(). # only enrich for nodes in df1 (synthesize nodes)

Likely prefer to do it locally

Describe alternatives you've considered

• Option g.nodes(labels_df, 'n', mode='enrich')
• Push to server vs do on client
