Add time import and tests for invalid date in email

Added `time` import in the eml_test.go and added two new test use-cases: `exampleMailPlainNoEncInvalidDate` and `exampleMailPlainNoEncNoDate`. The `exampleMailPlainNoEncInvalidDate` is used to check if the parser can correctly handle email with invalid date. Meanwhile, `exampleMailPlainNoEncNoDate` checks if the parser can correctly add the current date to an email that didn't specify a date. This will improve the parser's resilience and flexibility in handling various email scenarios.
