swow引擎下无法添加UDP协议监听

配置信息如下：
```php
[
'name' => 'UDP server',
'type' => ServerInterface::SERVER_BASE,
'host' => '0.0.0.0',
'port' => 9501,
'callbacks' => [
Event::ON_PACKET => ['className', 'methodName'],
],
'sock_type' => \Swow\Socket::TYPE_UDP
]
```
但是启动监听依然是TCP，检查发现`Hyperf\Server\SwowServer`并未根据sock_type做相应的调整。希望尽快调整，如果可以的话，我会在后续尝试提交修复。

Start with Hyperf\Server\SwowServer and trace how the server configuration creates its listener. Read the handling of the sock_type option and compare it with the configured UDP example. Done means a Swow server using Socket::TYPE_UDP starts as a UDP listener and accepts packet callbacks instead of starting as TCP.
