Error on retrieving Firewall if there is a rule with "any" port

[stefangeorgescu]

$firewall = $this->client->firewalls()->getByName('name'); I'm receiving the following error when retrieving a Firewall which has a rule with an "any" port:

` PHP Fatal error: Uncaught TypeError: Argument 5 passed to LKDev\HetznerCloud\Models\Firewalls\FirewallRule::__construct() must be of the type string, null given, called in /vendor/lkdevelopment/hetzner-cloud-php-sdk/src/Models/Firewalls/Firewall.php on line 112 and defined in /vendor/lkdevelopment/hetzner-cloud-php-sdk/src/Models/Firewalls/FirewallRule.php:48 Stack trace:

The issue should be easy to resolve adding null to the $port parameter type casting in FirewallRule.
