Incompatible with PHP 8.0

Hi there,

I’m reaching out on behalf of WordPress.com related to an issue reported by one of our users. During testing I found that the most recent version of this plugin (1.3.3) is not compatible with PHP 8.0. When used together, the following fatal is thrown. I tested this with all other plugins deactivated on WordPress 6.0.1.

I do see that a thread was previously opened about this [here](https://www.ads-software.com/support/topic/login-logout-menu-plugin-does-not-work-in-php-8-0/) where it was reported that the latest update was compatible with 8.0 but this does not appear to be true.

Fatal error: Uncaught Error: Call to undefined function create_function() in /srv/htdocs/wp-content/plugins/baw-login-logout-menu/bawllm.php:13
