Feature Request: Implement Refresh Token Functionality

[Adão Feliz]

Hello twikit Team,

First of all, I want to congratulate you on creating such an amazing library.

I'm currently using twikit, and I noticed that there isn't a built-in way to refresh the authentication token/cookie. Implementing refresh token functionality would greatly enhance the usability of the library, particularly for long-running applications that need to maintain a session without always requiring a new login.

Thanks for considering this enhancement, and for your continued work on twikit!
