[POC]: include potential positionsV2

[ChefMist]

POC to check if positionsV2 is preferred. positionsV2 is also more similar to CLPositionManager.positions(tokenId) https://github.com/pancakeswap/pancake-v4-periphery/blob/main/src/pool-cl/CLPositionManager.sol#L425

Copied out from BinPositionManager positionsV2 and positions

function positionsV2(uint256 tokenId)
        external
        view
        returns (
            PoolKey memory poolKey,
            uint24 binId,
            uint128 binReserveX,
            uint128 binReserveY,
            uint256 binLiquidity,
            uint256 totalShares
        )
    {
        TokenPosition memory position = _positions[tokenId];

        if (PoolId.unwrap(position.poolId) == 0) revert InvalidTokenID();
        poolKey = _poolIdToPoolKey[PoolId.unwrap(position.poolId)];
        binId = position.binId;

        (binReserveX, binReserveY, binLiquidity, totalShares) = binPoolManager.getBin(position.poolId, position.binId);
    }

    function positions(uint256 tokenId)
        external
        view
        returns (PoolId poolId, Currency currency0, Currency currency1, uint24 fee, uint24 binId)
    {
        TokenPosition memory position = _positions[tokenId];

        if (PoolId.unwrap(position.poolId) == 0) revert InvalidTokenID();
        PoolKey memory poolKey = _poolIdToPoolKey[PoolId.unwrap(position.poolId)];

        return (position.poolId, poolKey.currency0, poolKey.currency1, poolKey.fee, position.binId);
    }
