title: tqdm: extract time passed + time remaining?
body: <p>I have been going over the <a href="https://github.com/tqdm/tqdm" rel="noreferrer">tqdm</a> docs, but no matter where I look, I cannot find a method by which to extract the <strong>time passed</strong> and estimated <strong>time remaining</strong> fields (basically the center of the progress bar on each line: <code>00:00&lt;00:02</code>).</p>
  
  <pre><code> 0%|          | 0/200 [00:00&lt;?, ?it/s]
    4%|▎         | 7/200 [00:00&lt;00:02, 68.64it/s]
    8%|▊         | 16/200 [00:00&lt;00:02, 72.87it/s]
   12%|█▎        | 25/200 [00:00&lt;00:02, 77.15it/s]
   17%|█▋        | 34/200 [00:00&lt;00:02, 79.79it/s]
   22%|██▏       | 43/200 [00:00&lt;00:01, 79.91it/s]
   26%|██▌       | 52/200 [00:00&lt;00:01, 80.23it/s]
   30%|███       | 61/200 [00:00&lt;00:01, 82.13it/s]

  <p><code>tqdm</code> works via essentially printing a dynamic progress bar anytime an update occurs, but is there a way to "just" print the <code>00:01</code> and <code>00:02</code> portions, so I could use them elsewhere in my Python program, such as in automatic stopping code that halts the process if it is taking too long?</p>
