🐛 Bug Report: Limit on subscribed subreddits

[BugZappa]

Crate version 0.35.1

Describe the bug

It appears the old LIbreddit bug still plagues RedLib where if the cookie containing subscribed subreddits reaches the maximum size limit of 4096B then RedLib will refuse to subscribe to anymore subreddits.

Steps to reproduce the bug

1. Follow this old guide on importing reddit subscriptions to RedLib (Ideally you want a lot of subscriptions)
