Make decryption of logins and pwd compatible with v144
A simplified script to decrypt Firefox passwords stored in the 'logins.json' file, using the master_key from 'key4.db'. This script is based on the original work by @lclevy but has been refactored for clarity and simplicity, focusing only on modern Firefox versions that use key4.db and logins.json.
Added information about the fork 'firepwd-ng.py' and its purpose.

With this PR we make firepwd compatible with AES256_CBC decryption as implemented since v144.
However, I had to make a choice here since it's just a quick patch and not a complete rewrite.
The stay compatible with older versions, I chose to check for the masterkey length (in stead of algo_oid) and depending on that, picking the right decryption scheme.
