Ratio2xFallbackCLRSOracleL2
Gets the exchange rate between the underlying asset and the peg asset by using: 1. the price from a Chainlink price feed or a Redstone Oracle with one of them being used as main source and the other one acting as a fallback if the main source fails for any reason. Reverts if fetched rate is 0. 2. set into ratio with another price fetched the same way. I.e. it is possible to do Chainlink Oracle / Chainlink Oracle. E.g. wstETH per 1 weETH on a L2 via CL feeds.

instead. Only implemented for
backwards compatibility.
FALLBACK_ORACLE2_MAIN_SOURCE
function FALLBACK_ORACLE2_MAIN_SOURCE() public view returns (uint8)
which oracle to use as main source: - 1 = Chainlink ONLY (no fallback) - 2 = Chainlink with Redstone Fallback - 3 = Redstone with Chainlink Fallback
