Ensure that the deployed bytecode is properly formatted hex to ensure
that an empty value is not returned. This should never happen but is a
sanity check to ensure that unexpected values are not returned.

fixup

feat: Add dai to indexer

chore: Remove Kovan

op-node: P2P scorer refactor

op-node: implement new layered p2p connection gater

op-node: refactor scorer to decouple connection-gater, implement connection-gater with layered functionality

fix(proxyd): avoid caching tx hash based methods

op-node: Add gossip scores to peer store and opp2p_peers output

contracts-bedrock: dispute game factory event

Adds an event that is emitted when a dispute game implementation
is added to the dispute game factory contract. This will make
it easier to track the state of the contract.

op-node: GC for peer scores

contracts-bedrock: seize and split gas management

feat(op-challenger): L2OutputOracle Filter Query.

Ensure that a constant amount of gas is passed to each account
when splitting up the seized bond. We can assume that the recipients
will be able to receive ether with 30,000 gas. It is the end user's
fault if they do funny business in a fallback function and cannot
receive the ether. We also cannot revert if the transfer fails
because a malicious entity could prevent all other entities from
receiving their funds. Previously, the amount of gas sent to each
recipient was different and also based on the amount of gasleft
in the execution. The problem with using gasleft here is that
gas estimation will result in enough gas being used for the most
gas guzzling call to be used for each of the calls.

op-service: Define an abstract Clock

op-node: Add extended peer store to store scores

Supports storing gossip scores for peers.

Provides by system and deterministic implementations so services can have a common abstraction over time functions that enables testing.
