Add LAN UDK Query Support and UT3 Servers on LAN Support

[Hornochs]

Goal of this PR is to Fix Issue #31

With this necessary changes:

• Allowing the possibility to send broadcast Packages https://github.com/Hornochs/opengsq-python/blob/022d30527d6f6c73889c6df63897196b601be330/opengsq/protocol_base.py#L14
• Adding possibility for Class to receive Broadcastpackages https://github.com/Hornochs/opengsq-python/blob/022d30527d6f6c73889c6df63897196b601be330/opengsq/protocol_socket.py#L18-L43
• Adding possibility to bind the port from which the package is getting sent https://github.com/Hornochs/opengsq-python/blob/022d30527d6f6c73889c6df63897196b601be330/opengsq/protocol_socket.py#L49-L52
• Adding base Protocol opengsq/protocols/udk.py
• Adding Protocol opengsq/protocols/ut3.py to parse UT3 specific Values like GameID and including Pattern translation
• Adding Test tests/protocols/test_ut3.py So that the UT3 servers can be parsed

Testing this for other is not that easy, I can't put an online Server like on Nadeo titles because the communication happens over Broadcasts, which can't be routed via Internet. So there needs to be a UT3 Server hosted local in your network, even in the same VLAN!

There are more ways to test it:

1. On a LinuxVM install yourself a UT3 Dedicated Server: https://linuxgsm.com/servers/ut3server/
2. Download a prepared UT3 Dedicated Server from my webspace: https://static.3fu.de/ut3server.tgz - Caution! Package Dependencies are not fulfilled, look in the linuxgsm Link what packages are needed to be installed.
3. Run on your windows machine UT3 and start a LAN Server

Can you also generate the tests results by handler.enable_save = True? Thanks.

[Hornochs]

Sure, new Test results are there

[BattlefieldDuck]

Can you run the tests with handler.enable_save = True locally? It should generate the protocol response files, then you can comment the # handler.enable_save = True like other tests case.

So an example response of the protocol will be visible on the docs. 😄

Aaaah lol! Sure is appended :)
