v3.12.1

This is primarily an emergency hotfix for non-super Twitch key generation not saving the key to the configuration file.

Additionally changed the API endpoint used for Twitch channel follower queries. The hitherto-used helix/users/follows was deprecated in February 2023 and is scheduled to be shut down on September 12th. The new endpoint requires additional OAuth scopes, so a new key will have to be generated for the !followage command to work.

• Refactored the Webtitle plugin slightly
• Now generally uses .assumeUnique instead of .idup wherever applicable
• Fixed the CircleCI build script always failing to fetch the compiler due bash set -u
