What version of the csv crate are you using?

csv 1.3.0

Briefly describe the question, bug or feature request.

When the last line of the csv data is a comment, deserialization results in a CSV error stating that the found record does not have the appropriate number of fields when the expectation is that the line should be ignored all together since it starts with the comment character. Example error message: CSV error: record 2 (line: 5, byte: 70): found record with 1 fields, but the previous record has 3 fields

Include a complete program demonstrating a problem.
