AI read : 10ms x 20 samples

- Periodics
  ㄴ Analog read:  0 to 9 pin, 100ms x 50 samples = 500ms time window
- Analog read value
  ㄴ 평균을 위한 복수의 Analog read data를 링 형태로 저장 (기존에는 배열 재정렬, 연산속도 향상 필요)
  ㄴ 평균에 의한 정밀도 향상으로 floating 연산 후 factor 곱하여 송신
- MC9
  ㄴ not responsed 디버그 메시지 주석 (추후 디버그 모드 개발 예정)
- Init
  ㄴ AO, MC9 중복 초기화 방지를 위한 리턴 값 추가
