Twitch announcements don't show up on the overlay

[drillskibo]

A moderator using /announce would not see their message appear on the screen at all.
They should appear with a special background/style, maybe lock to top for a while.

🚧 Update after 94fe1f0
✨ Announcements now appear in the overlay.
🎨 The styling of the card match the one on the Twitch native chat, with borders on each side following the same color and pattern.
🐛 Animations on new message are broken for now, it will be worked on in short notice.
✅ The idea of locking to top for a short period has been accepted, and it will be added at a second time.

Here is a small codepen, which can be copy/paste and to match fully the native Twitch border gradient colours INCLUDING the border-radius compatibility with CJ Overlay Chat Cards: https://codepen.io/yuliyanstefanov/pen/PoaQvRy?editors=1100

Announcements can also pin themselves on top of the chat or do different things based on the color.
