json과 orjson의 사용성능 비교하기위해 테스트코드를 작성하였습니다.
pydantic.BaseModel을 상속한 데이터클래스에 유니코드를 포함한 임의의 데이터를 입력하는 방식으로
1개부터 1000개까지 생성하고 json, orjson으로 직렬화합니다.
각 테스트코드에서 직렬화에 소요되는 시간을 측정한 뒤 별도의 json 파일에 기록한 뒤, 도식화된 결과를 확인합니다.
측정된 시간은 ms(milliseconds) 단위로 기록됩니다.

작성된 테스트코드의 실행결과와 test_4_compare_serialized_data.py에 명시해둔 부분을 확인하면 알 수 있듯이
json.dumps()와 orjson.dumps()로 직렬화된 데이터는 서로 다른 형태를 가지고 있습니다.
하지만 각각의 직렬화된 데이터를 json.loads()와 orjson.loads()로 역직렬화한 데이터는 서로 같은 형태를 가지고 있습니다.
그렇기 때문에 기존에 json.dumps()로 직렬화된 데이터를 orjson.loads()로 역직렬화해도 문제가 없습니다.
