add a helper function to wait for element

[kmike]

Something like splash:wait_for_element(css_selector, timeout, poll_interval).

It should do something like this (untested):

function Splash:wait_for_element(css, timeout, poll_interval)
  return splash:with_timeout(function()
    while not splash:select(css) do
      splash:wait(poll_interval)
    end
  end, timeout)
end

Hey @kmike I did a similar method here but gave me high cpu usage. I will be testing this one out

Edit: Definitely worked fine in my production scripts

with_timeout runs even after selecting the css, stops only when timeout is met
