Goals:

We faced an issue with batch transform on sagemaker where parsing for text with escape chars (e.g. :point_down:). This PR fixes the way csv is parsed and add tests for complex input.

2,efgh\, with comma
3,ijkl with \"quote\"
4,mn\\nop with newline
5,qrst with \\ backslash
6,uvwx with both\, comma and \"quote\"
7,yzab with newline\\nand comma\,
