Write the Django API functions to handle the requests to import data from the scraping scripts

Depending on the decision for issue #11, the Django API functions will work differently. If we have decided to not do a .exe file, we can just create one HTTP request function to initialize scraping and channeling the output from the scrapes directly into our database with Django's ORM model. If we decide to use a .exe file, we probably have to create multiple API functions to handle the output from the scraping differently depending on which source we scraped them from. ** The key idea behind the functions is to convert the json data into the django models before sending them into the database. We might include some logic behind how we will update key entities like providers and sites to solve the chicken-egg problems

先解决 issue #11 中的决策，然后检查导入流程涉及的抓取脚本、Django API 函数和 ORM 模型。完成的标准是，所选的请求路径能够将 scraper JSON 转换为 Django 模型并持久化，同时处理 provider 和 site 的更新，且不存在尚未解决的实体顺序问题。
