Adding a session_file argument to the Duolingo constructor.

Which will be read and checked if given, and then the new jwt will be written to.

Should there be an option to read from a string directly? If a user wants to decide how to store a JWT. Since there is no standard way to do this, you don't have to force storing into a file.

[SpangleLabs]

Hmmm.. good point, could just add an optional jwt=None parameter, then move around some stuff in _login(), does that sound good to you?

[igorskh]

I don't fully get it. Do you want to make a generic jwt argument? How would you distinguish between a file path string and a string with JWT? One option I see is to accept only JWT string and the user is responsible for reading from file. Or doing some string parsing to detect a type.

How's this looking now?

Looks good to me
