Add getWrapperClass() to packet type

[spring-dependency-management]

There is no other way to get a packet wrapper for a given type other than a huge if else chain

With this, you can do:

PacketWrapper<?> wrapper = ReflectionUtil.createInstance(
    packetReceiveEvent.getPacketType().getWrapperClass(), new Class[]{PacketReceiveEvent.class}, packetReceiveEvent
);


public static <T> T createInstance(Class<T> clazz, Class<?>[] types, Object... args) {
  try {
    Constructor<T> constructor = clazz.getDeclaredConstructor(types);
    constructor.setAccessible(true);
    return (T)constructor.newInstance(args);
  } catch (Exception e) {
    throw new RuntimeException(e);
  }
}
