Finish interactive extension

[kMutagene]

Tis PR

• adds a DisplayOptions type equivalent to Plotly.NET that for example controls how cytoscape.js is referenced in rendered html
• uses Giraffe.ViewEngine DSL for creating type-safe html instead of relying on template strings
• updates docs to use one single global cytoscape.js reference for all graphs on a page
• Finishes Cyjs.NET.Interactive:
  • uses DisplayOptions to use require.js in notebooks
  • The problem was that the way of trying to render cytoscape graphs with a function does not work:

    let x = () => {
     fsharpCyjsRequire(['cytoscape'], function(cytoscape) {
         // using cytoscape here will not work
    });
    x(); // will not work
    fsharpCyjsRequire(['cytoscape'], function(cytoscape) {
    // using cytoscape here will work ! 
    });

This also closes #9

However, i'd like to discuss #12 and #11 before releasing this, as i would like to implement at least a basic top level API first, because working with DisplayOptions the way it is currently implemented is awkward because it is not coupled with the Graph, but just an argument of HTML.show/HTML.toGraphHTML

I'll merge this and implement #12 and #11 as discussed on main directly.
