Custom Toggle switch component

Create a custom toggle switch component for Thermal Design System (TDS).

---

The currently package `vue-js-toggle-button` is not reactively toggling the switch. For instance:

```js
commitFeature: {
    get: function() {
        return !!+this.settings.commitFeature;
    },
    set: function(value) {
        this.settings.commitFeature = value ? 1 : 0;
    }
}
```
