Hi
Please add support Sessions like Instaloader to import cookies from pickle file

[mikf]

from pickle file

Why?

gallery-dl can load cookies from cookies.txt files, same as youtube-dl, or from its config file: see Cookies

[GetPHP-IR]

I want to use instaloader's session files to login instagram by gallery-dl
When i convert the session to netscape format some config has dropped like:
.instagram
TRUE / FALSE section
And some others that make not usable
