Show custom image packs from spaces and account data

[evoL]

MSC2545 specifies that image packs can be referenced in three places:

1. the room itself though an m.room.image_pack state event
2. the canonical space of the room
3. the user's account m.image_pack.rooms account data event for packs meant to be available globally

Based on my observations, space and global image packs are not implemented right now. It would be great if we could see those emojis/stickers in the pickers as well.

Is it possible by any chance that you have image packs with both the MSC old unstable name and the new stable name in your account data? 🤔
