Custom Stickers & Emoticons (MSC2545) like it works in Cinny or FluffyChat

Your use case

What would you like to do?

I would like to see native stickers and custom emoticons support in Element, like it works in Cinny or FluffyChat.

Why would you like to do it?

Clients like Cinny already using native sticker packs instead of integrations in Element. It's work faster and have simplified manage process.

How would you like to achieve it?

Cinny using this specs, and it's work perfectly. I also write a small tool to manage sticker packs. Need to just copy logic to Element :)

I can't write code for this for itself that I don't know Kotlin, but think it's a very important feature, so I created this issue.

Have you considered any alternatives?

I think this'd be great too especially knowing that an existing, functional, Matrix compatible implementation already exists.
