title: Automate pdfminer.six LAParams configuration
body: <p>We're building an app and we need to extract data from many pdf e-books. They have different formats, font sizes, line spaces, etc...</p>
  <p>We're currently configuring the <code>pdfminer.layout.LAParams</code> for each pdf and it's not feasible.</p>
  <pre><code>LAParams(line_overlap=0.5, char_margin=2.0, line_margin=0.3, word_margin=0.1, boxes_flow=0.5, detect_vertical=False, all_texts=False)  
  </code></pre>
  <p>The biggest issue is that for some books, paragraphs aren't recognized so we end up having only one-line paragraphs.</p>
  <p>Is there any known way to automate the configuration for each pdf?</p>
