map constructor with object as property

[ttdonovan]

This may not specifically be an issue with leaflet-rs and more of a wasm_bindgen question but looking for suggestions how to approach this. Thanks in advanced.

Example of the JS constructor that I am wanting.

const map = L.map("map", {
  crs: L.CRS.Simple,
  minZoom: -3,
  maxBoundsViscosity: 1.0,
});

What to do in Rust or how to add L.CRS to the bindings?

#[derive(Serialize, Deserialize)]
#[serde(rename_all = "camelCase")]
struct MapOptions {
    // crs: ???, // this is JS object... L.CRS.Simple
    min_zoom: i32,
    max_bounds_viscosity: f64,
}

...

let options = JsValue::from_serde(&MapOptions {
    // crs: "L.CRS.Simple".to_string(), // how to make this a serializable JS Object...
    min_zoom: -3,
    max_bounds_viscosity: 1.0,
}).expect("Unable to serialize map options");

let map = Map::new("map", &options);

My goal is to add a game map and here is my feeble attempt...
