CR newline not supported

[molsonkiko]

Files with CR newline were not properly parsed, and instead gave some sort of error. The bug was in CsvQuery/Csv/CsvSettings.cs.

Doesn't seem like this was a bug per se, since you apparently made the conscious choice not to support this.

That said, I have worked with CSV files that use CR newline, and I figured I'd fix this.

I'll open a PR.
