- * @dev Auxiliary library for PoolPriceOracle, offloading most of the query code to reduce bytecode size by using this
- * as a linked library. The downside is an extra DELEGATECALL is added (2600 gas as of the Berlin hardfork), but the
- * bytecode size gains are so big (specially of the oracle contract does not use `LogCompression.fromLowResLog`) that
- * it is worth it.
