Improve resilience regarding downloads #49

First of all, thank you very much for this script to download the books. It's awesome!

I faced a few problems while downloading the books using a flaky connection. If the network fails, the script stops. Even though it doesn't attempt to redownload already downloaded books, it still makes a request for them anyway.

This PR improves upon this. The script will not perform requests before checking if the books are already downloaded when it resumes operations after a fail. It speeds up the download of missing books after a failure recovery. Additionally, if for some reason the request fails, the script now reports this error and sleeps for 30 seconds. After it continues downloading the next book in the queue. This prevents the user from regularly checking if the script is still working.

Thank you again for your script!
