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"

首先定位 parser 对跨行引号的处理，并检查 parser 选项的定义方式。添加一个选项，将未转义的引号视为普通字段内容，然后验证示例输入会生成彼此分开的行，而不是一条持续的行。
