Add address and port to constructor in JavaScript API

[engbergandreas]

We should update the JavaScript API to accept a port and address without having to create and import the socket module separately, similar to what we did we the Python API.

Might actually be uneccessary since the module.exports handles it

yeah I think we have this. Basically when I use the api I do something like this:

var api = window.openspaceApi(host, 4682);
