[feature request] Elevated message flag? about showmy.chat HOT 1 OPEN

Twitch's support article for elevated messages.

Quick summary of the feature: chatters can pay $5, $10, $25, $50, or $100 to affix their message to the top of the native Twitch chat window for 30 seconds, 1 minute, 1min 30s, and so forth. In addition to the affixation, the message itself gets a lil elevated status next to it, as well as a little bubble that says how much the chatter spent:

Per the above support article, elevated messages are an experiment running "for 4 weeks starting at the end of September." As a result, I doubt we're going to see a whole lot of movement from tmi.js and ComfyJS to support this immediately, and we might need to wait for the experience to exit experimental phase before it's supported well enough for showmy.chat to use.

If and when it is supported, though, I do think it'd be worth exploring:

• Whether the amount contributed is exposed
• Whether the amount contributed might be displayed in a currency other than USD
• Whether the affixation time is exposed
• Whether we want to do anything fancy for the duration that the message is elevated
