Generic extension to visualize Graphoscope graphs with Cytoscape.NET

### Description

This is a 'glue' function that reduces friction between usage of Graphoscope and Cytoscape.NET.

When working with graphs, visualization is a common task. This would ideally work in a smooth pipeline, where a function transforms the input graph to a `CyGraph` for visualization, which can then further be used in the pipeline for additional styling, etc. before display

(the following is just a rough draft, might be not directly possible to implement it like this)

```fsharp
FGraph.init(...)
|> FGraph.toCyGraph
|> CyGraph.withStyle (...)
```
