Remove the duplicate logic in connection classes

[ItsDrike]

There is a couple of methods with duplicated logic. Maybe we should do it in one method with dict or possibly with an enum class?

from enum import Enum

class ValueType(Enum):
    FULL_NAME = "Q"
    ...

def write_value_with_type(self, value: int, type: ValueType) -> None:
    self.write(self._pack(type.value, value))

write_value_with_type(123, ValueType.FULL_NAME)

Potentially no longer relevant if mcstatus will move to using mcproto as dependency (however that could still take a while, as mcproto doesn't yet have complete support for java, and currently completely lacks bedrock support)
