Binding for wake word engine (Porcupine). It initializes the JavaScript binding for WebAssembly module and
exposes a factory method for creating new instances of the engine.

When the WebAssembly module has finished loading, if a callback function was provided via the PorcupineOptions object,
it will be invoked. Otherwise, use `.isLoaded()` to determine if Porcupine is ready.
