Please update plugin for future MySQL compatibility

Hello,

the plugin uses this condition to call X() and Y() functions ONLY for MySQL version below 5.6.1

if (function_exists(‘mysqli_get_server_info’) && $wpdb->dbh && version_compare(preg_replace(‘#[^0-9.]#’, ”, mysqli_get_server_info($wpdb->dbh)), ‘5.6.1’, ‘<‘)) {

MySQL version greater than 5.6.1 uses ST_Contains() function, which is fine for MySQL 8
