jh.chun c72349cf13 NUS characteristic: MITM 인증 완료된 연결만 접근 가능하도록 수정 
- SEC_OPEN -> SEC_MITM
- 기존에는 SoftDevice 레벨에서 인증 전 write를 차단하지 않음

jh.chun a0aa180ef1 DFU characteristic: MITM 인증 완료된 연결만 접근 가능하도록 수정 
- SEC_OPEN -> SEC_MITM
- 기존에는 페어링 완료 전에도 DFU characteristic write 가능, BLE SMP 타임아웃(30초) 전에 wirte하면 부트로더로 재부팅되어 인증 없이 DFU 모드 진입 가능했음
