Erreur with wpdiscuz-ajax

Hello,

We use a custom structure for our wordpress ( based on bedrock ), and there is an issue with loading the wp-load.php file, since we don’t have a wp-content folder.

The problem comes from /utils/ajax/wpdiscuz-ajax.php line 162

function wpdiscuz_ABSPATH() {
    $path = join(DIRECTORY_SEPARATOR, ["wp-content", "plugins", "wpdiscuz", "utils", "ajax"]);
    return str_replace($path, "", __DIR__);
}

A simple fix would be to allow users to override this constant, like this for example :

function wpdiscuz_ABSPATH() {
    $env = getenv('WPDISCUZ_ABSPATH');

    if($env) {
        return $env;
    }

    $path = join(DIRECTORY_SEPARATOR, ["wp-content", "plugins", "wpdiscuz", "utils", "ajax"]);
    return str_replace($path, "", __DIR__);
}

It would allow modern WordPress stack to work along with wpdiscuz ajax functions.
