Update Lib

[FsDk-es]

Me gustaría poder agregarle soporte a UnrealiRCD 5.xX/6.xX a esta librería..

Feel free to make the necessary changes to support newer UnrealIRCd versions, I would be happy to accept a PR. I myself haven't touched the IRC protocol or any servers in many years, so don't expect any updates from my side.
