Load mod badge information from the FFZ API instead of assuming the URL.

This lets us load all sizes of the emote if they are available.

Channel with all versions of the mod badge: https://api.frankerfacez.com/v1/room/pajlada
Channel with only one version of the mod badge: https://api.frankerfacez.com/v1/room/apa420
Channel with no mod badge: https://api.frankerfacez.com/v1/room/forsen
