This builder allows easier access to already changed contract addresses, and entity attributes while avoiding duplicated entries.
This is needed to implement the update markers on balancer substreams.
In case we get negative balances, which happens sometimes e.g. in balancer and seems to be due to some rounding issues within the protocol, we simply clip the balance at 0 so we never emit negative balances as tycho-indexer the upstream system will interpret the balance bytes as unsigned integers.
