title: Ordered list of redux-form fields
body: <p>Do you know how can I get the ordered list of field names from given form? <a href="https://redux-form.com/7.4.2/docs/api/reduxform.md/#instance-api" rel="nofollow noreferrer">Instance API</a> has a property called "fieldList" and it's an array but it's not in correct order. (<code>ordered list = [firstFieldName, secondFieldName, ...]</code> so what I need is a list of field names in order they appear in my form - top to bottom)</p>
  
  <p>Also the redux-form' action <code>'@@redux-form/REGISTER_FIELD'</code> is dispatching out of correct form order so I guess it's not what I need here...</p>
  
  <p>(My redux-form version: <strong>7.3.0</strong>)</p>
