Minecraft (spigot) behaves differently. It does not support empty
requests. This is a deal breaker for the SimpleClient implementation.
The implementation is mutch simpler but in limits the exec support to
not support multi packet responses.
Initially it was the idea that this would be version 2 of the
https://github.com/hamburghammer/rcon lib but I changed my mind and
decided to make a new Project out of it.
It has formally nothing to do with the original lib.
