Pull Request Overview

This PR enhances Excel type detection for password-protected files and refactors the encryption-related test cases to support XLSX, XLS, and CSV in both file and stream modes.

• Refactored EncryptDataTest to parameterize read/write scenarios across XLSX, XLS, and CSV.

• StringUtils is not imported; add the appropriate import (e.g., import cn.idev.excel.util.StringUtils;) to avoid compilation errors.

        boolean hasPassword = !StringUtils.isEmpty(readWorkbook.getPassword());
