Support for PhpSpreadsheet 3.x

[arce701]

First of all, thank you for maintaining this excellent package! Laravel Excel has been a cornerstone in our projects for handling spreadsheet operations efficiently.

Feature Request

I would like to request support for the latest PhpSpreadsheet 3.x series in a future release of Laravel Excel.

Current Situation

• Currently using Laravel Excel 3.1.62
• Limited to PhpSpreadsheet ^1.29.x due to package constraints
• PhpSpreadsheet 3.x brings significant security improvements and new features

Benefits of Supporting PhpSpreadsheet 3.x

• Enhanced security (resolves multiple CVE vulnerabilities)
• Performance improvements
• Access to new features and improvements
• Better compatibility with modern PHP versions
• Future-proofing our applications

Impact

This update would help many developers keep their applications secure and up-to-date while continuing to enjoy the excellent features of Laravel Excel.

Thank you for considering this request. Let me know if you need any additional information or if there's any way I can help with this transition.

I hope this will be addressed. latest version for phpoffice/phpspreadsheet is v4. I am forced to uninstall this Laravel Excel for now since I heavily used the phpspreadsheet package. :(
