Store library of emotes by ID for referencing the emote tags sent by every message.

Twitch IRC sends emote tags with every message by emote ID. If we store these in a table, we can reference the id for emote analysis later. The internet says the legacy endpoint for getting all emotes should still work. It's reference is here. It also includes links to images as well, which is a lot of data but we can get those later if we need them.
