Additional Context

Telegram seems to be gearing up to allow mixed-media sticker packs. From yesterday's update:

Mixed-Format Sticker Packs

Removed the fields is_animated and is_video from the class StickerSet.

Added the field format to the class InputSticker.

Not sure if they've made any other announcements yet, but the StickerSet class may need to be reworked.
