This PR adds a sender-based rate limiter to proxyd. This rate limiter throttles eth_sendRawTransaction requests based on sender in order to prevent abusive behavior on the sequencer.

Integration tests have been added to test this functionality.

This reverts commit a46a2f76.

fix(op-node): Use a reader to parse `SystemConfig` update events

Adds json struct tags to the `CrossDomainMessage` type.
This is useful for reading and writing this type to
a file. The `Data` field must be updated to a `hexutil.Bytes`
in a subsequent PR.

Remove logger

Use `hexutil.Bytes` in the `Withdrawal` type so that
when writing and reading from JSON, it correctly serializes
the data as a 0x prefixed hex string. Without this, it will
some base64 looking serialization. Be sure to cast to a byte
slice before doing any abi packing, otherwise it will cause
errors.

Fix

Fixes a bug in the DTL that caused it to not be able to sync beyond the
deposit shutoff block. This would happen because the TO block would be
less than the FROM block which would cause certain providers to throw an
error.

op-node: add better docstring for storage slot

feat(ctb): set up SystemConfig in step 1

Moves the SystemConfig upgrade/initialization logic into Step 1 of the
SystemDictator contract. This means that the Sequencer is correctly able
to spin up between steps 2 and 3.

The unsafe block signer is stored at a magic storage
slot that decouples `solc`'s storage layout system from
being able to move the storage slot accidentally.

This adds in a better docstring so that its obvious
how the value is computed.
