Unfortunately, I have to drop some supported PHP versions.
PHP 8 is strict about return types which were introduced in PHP 7, so I have to drop support for PHP 5.4-5.6.
voidreturn type (now required in PHPUnit) was introduced in PHP 7.1, so I have to drop support for PHP 7.0
This PR will add compatibility with PHP 8.
