Price Feed Exists

Determine if a price feed for the given price_identifier exists. Returns true if there has been at least one on-chain update of this feed in the past. Note that a false answer may mean that the feed exists, but simply has never been updated on Aptos. In this case, you can invoke update_price_feeds to pull an update on-chain.
