PriceFeedWrapper

Returns the price of an asset that doesn’t have a direct feed from Chainlink.

Written as a generic implementation it can be used, for example, to retrieve the price of wstETH. Queries stETH / ETH feed and multiplies it by the exchange rate between stETH / wstETH before returning the price that it’s then used by the Auditor.
