Add wait option

[roniemartinez]

Some JS-enabled websites has multiple pop-ups (agree dialog -> newsletter dialog -> subscribe dialog -> now you can use the website) and these dialogs takes time. Adding wait will make sure that the setup handlers will wait first.

Option 1: Explicit

@select(text="AGREE", setup=True, wait=1000)  # or wait_for="visible"
def handler(element, page):
    with page.expect_navigation():
        element.click()

Option 2: Implicit
