Relates to elastic#109992 When I implemented binary comparisons for date nanos in elastic#111908 I failed to update the verifyBinaryComparisons rule, which implements another layer of type checking for binary comparisons, external to the type logic in the Expression classes. Since the unit tests for the expressions don't run the full query processing stack, this bug was invisible to them. Only full integration tests, such as the CSV tests I've added here, can catch this kind of error. The initial PR did not include these because we didn't have enough supporting functions (notably TO_DATE_NANOS) to write the tests. This PR fixes the issue by adding DATE_NANOS to the list of allowed types for binary comparisons in the verifier.
