XGMML download not working

[ErdaradunGaztea]

There's a problem with edge data containing sequences in tibble format. Turns out BioNet::saveNetwork(type = "XGMML") calls BioNet:::.XGMML.edges(), which in turn saves edge attributes in text; and this text requires string/integer/real values, not tibbles. Would reversing the parsing made to the sequence columns before saving with BioNet work? This would change

graph_from_data_frame(
  edges[["table"]],
  vertices = ag_data_nodes()
)

to something like

graph_from_data_frame(
  deparse_chains(edges[["table"]]),
  vertices = ag_data_nodes()
)
