WstETHCLRS2UniV3CheckCLRSOracle

Gets the exchange rate between the underlying asset and the peg asset by using: 1. wstETH Oracle price in combination with rate from Chainlink price feeds (or Redstone as fallback). combining those two into one rate resulting in wstETH <> someToken 2. result from 1. combined with a uniV3CheckCLRSOracle to get from someToken <> someToken2 e.g. when going from wstETH to USDC: 1. wstETH -> stETH wstETH Oracle, stETH -> ETH Chainlink feed. 2, ETH -> USDC via UniV3 ETH <> USDC pool checked against ETH -> USDC Chainlink feed.
