op-node/cmd/batch_decoder: Fetch batches

op-chain-ops: Migration fixes

INF-89 adds chain-mon docker builds to circleci

Provides a utility for fetching batches. It downloads all transactions sent
to the batch inbox & stores them for later inspection. It logs transaction
hashes that do not come from the authorized senders.

op-node/rollup/derive: Check origin of L2 unsafe head match new L1 origin

- Simplify import structure
- Add proper checks for invalids torage slots
- Add unit testing
- Remove need to run the TypeScript witness-generation steps

Each time we reach a new L1 origin in the EngineQueue stage, check it indicates the L2 block is non-canonical and reset if so.

op-node: fix and test finalization of sparse batches

feat(atst): Seperate react into a different build target

feat(ctb): Test for memory safety of `Bytes.slice`

fix(atst): Default chainId to undefined instead of 10

op-node: Set timeouts on http servers

op-node/p2p: Extend time out for discovery test

op-node/p2p: Use the new block signing hash when producing gossip

Both legacy and new hashes are still accepted to avoid incompatibility if other nodes upgrade before the sequencer is upgraded.
