title: Two consecutive fields having the same value make Papaparse fail?
body: <p>Parsing following file ( in my case with 'header:true' ) :</p>
  
  <pre><code>FN1,FN2,FN3
  A1,A2,A3
  B1,B2,B3
  C1,C1,C3
  D1,D2,D3
  </code></pre>
  
  <p>makes Papaparse fail on </p>
  
  <pre><code>Row 4 : Too few fields: expected 3 fields but parsed 1
  </code></pre>
  
  <p>Please note this is a stripdown of a much larger file where the consecutive values where deep down the file.</p>
  
  <p>Is this a bug or am I doing something wrong ?</p>
