CSV Verification

Write a function to verify if a given CSV file adheres to specified rules. The specific requirements are as follows: Each line of the CSV file contains multiple fields, separated by commas. The first field is a unique identifier for the data row and should not be duplicated. The second field should be in date format (YYYY-MM-DD) and must be a valid date. The third field should match the format for a standard email address. The number of fields should be consistent in every line. Write a program to read CSV data from standard input and then output the verification results.
