Implement native support for Price Oracles. A Price Oracle is used to bring real-world data, such as market prices, onto the blockchain, enabling dApps to access and utilize information that resides outside the blockchain. Add Price Oracle functionality: - OracleSet: create or update the Oracle object - OracleDelete: delete the Oracle object To support this functionality add: - New RPC method, `get_aggregate_price`, to calculate aggregate price for a token pair of the specified oracles - `ltOracle` object The `ltOracle` object maintains: - Oracle Owner's account - Oracle's metadata - Up to ten token pairs with the scaled price - The last update time the token pairs were updated Add Oracle unit-tests
The compilation fails due to an issue in the initializer list of an optional argument, which holds a vector of pairs. The code compiles correctly on earlier gcc versions, but fails on gcc 13.
