can you instead test these against getSlot0?

| bytes32 stateSlot = _getPoolStateSlot(poolId); | ||
| bytes memory data = manager.extsload(stateSlot, 4); |

this needs to be updated to an array of bytes32 that gets returned
| slot0 := mload(add(data, 32)) | ||
| feeGrowthGlobal0X128 := mload(add(data, 64)) | ||
| feeGrowthGlobal1X128 := mload(add(data, 96)) | ||
| liquidity := mload(add(data, 128)) |

needs to be masked to remove the other 128 bits of data from this data type

This util is helpful when someone wants to read all the global pool state. It is better than making multiple extsload calls.
