Feature: Options passed in as file

[canhorn]

I would like to pass in all my options for the Tool as a single file.

{
    "force": true,
    "assembly": "Blazor.BabylonJS.WASM",
    "source": [
        "https://raw.githubusercontent.com/BabylonJS/Babylon.js/master/dist/babylon.d.ts",
        "https://raw.githubusercontent.com/BabylonJS/Babylon.js/master/dist/gui/babylon.gui.d.ts"
    ],
    "class": [
        "Button",
        "MeshBuilder",
        "PointLight",
        "StandardMaterial"
    ]
}
