Implement a new Collectable API in AstAnalyser

[fraxken]

The idea is to implement a new way of collecting some of the data that JS-X-Ray is extracting and analysing along the way such as (mostly string located in the literal probe):

• URL
• Ips
• Hostname

Note

We could extend that list in future PRs (no need to integrate 10 of thems in the initial draft).

The API itself could look like:

const domainSet = new CollectableSet("url");

const scanner = new AstAnalyser({
  collectables: [domainSet]
});

console.log(Array.from(domainSet));

Note

Naming is not definitive and open to discussion

This datastructure would provide the following features:

• File and AST location (one entry can have multiple)
• Metadata

Also doing it this way make things easier when dealing with the EntryFileAnalyser API.
