===== BS2_RemoveAuthGroup=====
주어진 인증 그룹을 제거합니다.
==== 함수 ====
<code cpp>
#include "BS_API.h"

int BS2_RemoveAuthGroup(void* context, uint32_t deviceId, uint32_t* authGroupIds, uint32_t authGroupIdCount);
</code>
==== 파라미터 ====
  * [In] ''//context//'' : Context
  * [In] ''//deviceId//'' : 장치 식별자
  * [In] ''//authGroupIds//'' : 제거할 auth group id 리스트
  * [In] ''//authGroupIdCount//'' : auth group id 리스트의 크기
==== 반환값 ====
성공적으로 수행될 경우 ''BS_SDK_SUCCESS''를 반환하고, 에러가 발생할 경우 상응하는 에러 코드를 반환합니다.
