Note to self: Incorporate room-backed sticker packs.

Example: https://stickers.t2bot.io/pack/@travis:t2l.io/aLYBMlgmYx-Dimension-Huskies.json

The JSON has a subscription field which describes where to go looking for the sticker pack. The expectation is that a bot/client joins that room and tracks changes that way. The same event structure could be used for per-room stickerpacks.

Stickerpack event (currently):

This is now obsoleted by MSC1951 - custom emoji and sticker packs as rooms. This proposal had a few deficiencies which should be resolved by MSC1951, namely the inability for applications to subscribe to updates on packs.
