Feature: converting graphs to GFA

[aafshinfard]

Thank you for your work on gfapy;

In the documentation, I could not find a function to convert well-known graph data structures like igraph or networkx to gfa. Assume that we worked on a graph in Python and then we want to print it to a gfa file. One way is to iterate over the graph and add lines to a gfa instance, but it would probably be very useful and more convenient to have this implemented within gfapy.

Also, in a more general way, would be nice if we could have access to functions like add_graph_node() or add_graph_edge, that add the lines for nodes and edges without the user spelling the full line using add_line

Hi @aafshinfard, for sure it would be interesting to implement automatic conversion.

It is probably not so difficult to add basic functionality for it. Unfortunately I have not much time for that at the moment, since I am too busy with other projects.
