Not related to a problem

Describe the solution you'd like

An option (or default) to output the gfa file and a Bandage plot of the gfa file for a quick visual summary of the assemblies (perhaps in the full summary report). Alternatively, just the Bandage plot.

Describe alternatives you've considered

I've tried copying and renaming the assembly_graph.gfa output files from flye into the output dir, as it's possible to then make the Bandage plot. The .gfa files in the work directory aren't named by barcode so it's not possible to take them from there.
