title: Composer get progress output of install
body: <p>I am trying to find a way to get the progress output of a <code>composer install</code>. I would like to use this output to show a progress bar to indicate how far a long the command is and communicate this back to the frontend. This will be used for tracking tasks within a deployment.</p>
  
  <p>Currently I don't see a clean way to hook in and get a total step count and current step to display a progress bar. If this even currently possible or is there a workaround to get this data?</p>
