title: Ignoring generated protobuf files in pycharm
body: <p>I want my IDE to stop showing me the unreadable generated files when I search. Say I have a protobuf file <code>foo.proto</code> :</p>
  
  <pre><code>message bar {}
  </code></pre>
  
  <p>and I generate the python package <code>foo_pb2.py</code> (and the <code>foo_pb2.pyi</code>). When searching (double up arrow button/shift) for foo I'd like to see the protobuf definition in <code>foo.proto</code> but not the generated code in <code>foo_pb2.py</code>. </p>
  
  <p>I managed to get the first thing to work by installing the "Protobuf Support" addon but I cannot find anything for the second part.</p>
  
  <p>Similarly, when using the "Declaration" functionality (cmnd + click) I get sent to <code>foo_pb2.py</code> file instead of <code>foo.proto</code>. Is there a way to map these correctly?</p>
