title: Logstash parse multiline CSV file
body: <p>I have a CSV file with some fields which contain "\n". The field is in quotes, so it displays properly on excel or using pandas in python. However using the CSV filter in logstash doesn't work properly and gives either CSV parse error or wrong fields. Anyone who has experience with this before? </p>
  
  <p>I also saw this issue on github: <a href="https://github.com/logstash-plugins/logstash-filter-csv/issues/34" rel="nofollow noreferrer">https://github.com/logstash-plugins/logstash-filter-csv/issues/34</a> but it's a year old.</p>
