feat: automated cookie grabbing for config.json (must be logged in on chrome)

[ahuangg]

current approach:
user has to go to the website manually to grab the cookie

requirements:
user has to be logged in to weibo.cn on the Chrome browser

solution:
grabs the cookie from the browser and adds it to the cookie section in config.json when the crawler is ran for the first time

future:
if the cookie becomes invalid we can run this functionality

目前有一点点问题，如果是在 Windows 的 WSL 下运行的话会报错：

Failed to obtain weibo.cn cookie from Chrome browser: [Errno 2] No such file or directory

原因在于 WSL 下确实不会有 Chrome 的 cookie.

我准备稍后加一个 try except 来让这种情况下显示的报错信息更明确一些。
