Breaking changes, update required

The Twitter extension is using a proxy on Heroku that’s been migrated to Fly.io due to Heroku removing free tiers.

Please update your Twitter extension before the end of the month:

1. Download the new Twitter.sef file
2. Install the extension. Press Yes when SAMMI asks you to override the extension. Press No when SAMMI asks you to replace the deck - this is NOT required.
3. You’re up and running again!
