`data-baz-async="viewport"`

• ➕ [added] support for async bazFunc calls via IntersectionObserver. In browsers without IntersectionObserver support, falls back to the equivalent of setTimeout(bazFunc, 1, node). Check out _async example

/* (old) sync call */
<div data-bazooka="init-time">
    will be called on `Bazooka.refresh()` / `Bazooka.watch()`
</div>

/* (new) async call */
<div data-bazooka="init-time" data-baz-async="viewport">
    will be called when in viewport
</div>
