/**
 * @title MultiFeedAdapterWithoutRounds
 * @author The Redstone Oracles team
 * @dev This abstract contract serves as an adapter for multiple data feeds, facilitating 
 * the updating and retrieval of oracle data values independently.
 *
 * Key details about the contract:
 * - Values for data feeds can be updated using the `updateDataFeedsValuesPartial` function
 * - Unlike the previous version (RedstoneAdapterBase), this adapter allows updating any set of data feeds, 
 *   with each update being made independently.
 * - Updates are highly independent. Each data feed update is attempted separately, ensuring maximum possible
 *   updates without reverting the entire transaction if some of them fail. Both successful value updates and
 *   update skips due to failed validation are represented in corresponding events.
 * - Efficient storage usage: Related timestamps and values are packed into a single 32-byte slot when possible.
 *   If a value exceeds the slot capacity, it is stored in the next slot, with one bool prop (isValueBigger) indicating the storage method used.
 * - All data packages in the Redstone payload must have the same timestamp. Invalid timestamps (too old or too new) will cause transaction reversion.
 * - The contract includes a built-in IPriceCalculator interface used by LayerBank and other projects
