/// @notice Acts as router that dispatches calls to corresponding price feeds.
///         - Underlying price feeds can be arbitrary, but they must adhere to Chainlink interface, i.e., implement
///         `latestRoundData` and always return answers with 8 decimals. They may also implement their own price
///         checks, in which case they may incidcate it by returning `skipPriceCheck = true`.
///         - Price oracle also provides "safe" pricing, which uses minimum of main and reserve feed answers. These
///         two feeds are allowed to be the same, which effectively makes it trusted, but to reduce chances of
///         this happening accidentally, reserve price feed must be explicitly set after the main one.
///         The primary purpose of reserve price feeds is to upper-bound main ones during the collateral check after
///         operations that allow users to offload mispriced tokens on Gearbox and withdraw underlying; they should
///         not be used for general collateral evaluation, including decisions on whether accounts are liquidatable.
