[BUG] from_json does not support input with \n in it.

[revans2]

Describe the bug
Because of how from_json works we don't have a way to support \n in the JSON input itself. I don't think this is likely to happen and we throw an exception if we run into it. But there is a Spark unit test that actually tries to do this, so we probably should figure out how to support it eventually.

Actually after looking at more real world data it is clear that this does happen, and we need to support it. I filed rapidsai/cudf#15277 in CUDF to help us address this.
