Support for PHP ^8.0

[mainadennis]

May you add support for newer versions of PHP. I keep on getting this error and I can't downgrade my PHP versions as my project is built around it.

[InvalidArgumentException] Package qcod/laravel-settings at version 1.0.9 has a PHP requirement incompatible with your PHP version, PHP extensions and Composer version: - qcod/laravel-settings requires php ^7.3 which does not match your installed version 8.0.11. - qcod/laravel-settings requires laravel/framework ~5.4.0|~5.5.0|~5.6.0|~5.7.0|~5.8.0|^6.0|^7.0|^8.0 but it is not present.
