[BUG] CUDF does not strip trailing white space after a quoted string value

[revans2]

Describe the bug
When spark sees a line like

"A"   ,"B"

It sees that there is white space after A, and because A is quoted it will strip off the quotes and the trailing white space. CUDF sees any white space at the end after the quote and assumes that all of the data should be a part of the string so it produces a value of "A"

Steps/Code to reproduce bug
We have an integration test for this in the CSV tests. test_basic_read for the file ints_with_whitespace.csv but with the schema for strings instead of bytes.

I filed rapidsai/cudf#13892 for this in CUDF
