Steps to Reproduce

1. Pull ( https://groups.csail.mit.edu/sls/downloads/movie/engtest.bio ) with file -https connector local csv as destination.
2. with reader option "{"sep" : "\t", "names": ["Tag","String"], "quoting": 3, "skip_blank_lines": "False"}"
3. Output still ignores/skips the blank lines.

[sheshan-doye-konvergeai]

This works if we give "skip_blank_lines": false. As spec.json recognise Boolean values in lower case.
