Enhancement: Add option for unescaped quotes in csv

Would be really nice if you could pass in an option to the parser to NOT try to escape quotes across multiple lines. Ran into this issue when the data feed I received didn't properly escape their double quotes so the parser didn't process the next lines properly. Ie in the example below everything is considered the first row.

ie:
row, some item, that is 16"
another row, that has something in it, no quotes
row3, has another, item with quote that is 12"

まず、複数行にまたがる引用符の parser における処理箇所を特定し、parser オプションの定義方法を確認します。エスケープされていない引用符を通常のフィールド内容として扱うオプションを追加し、その後、サンプル入力が1つの継続行ではなく別々の行を生成することを確認します。
