chore: add changeset

Removes an imported function that was not being imported
correctly in the docker setup. Inline builds the address
and throws an error in the case where the logic is unsafe.

Deletes dead contracts as well as re autogenerates
the `README.md` so that the latest contracts are reflected in it.

Also fixes some issues with the deployment scripts as well
as the genesis block creation script. The deployment artifacts
from the deployment are included in this PR.

Adds a script that will create the goerli genesis file

This allows scripts that depend on the git hash
at build/runtime to access it.

The precompiles need to be in the genesis file with 1
wei.

Adds the ability to publish the builder as well as the
gas-oracle for the canary releases.

refactor(contracts): Only check nextQueueIndex <= queueLength once

chore: add changeset

refactor(contracts): remove unused imports

test(contracts): reduce target costs to account for gas saving

test(contracts): Add a test for block hash in logs

The cost of running benchmarks was determined by running them on the contracts at regenesis/0.4.0 (98e02cfa/ PR #1148), then applied to the benchmarks here to calculate both absolute and relative amounts saed

I observed a very small savings from increasing the optimizer runs,
and no noticable impact on compile time

Although we're quite happy when the CTC gets cheaper, we want to know about it
and lock-in the savings.

Previously our gas specs have only printed the values they record,
without ensuring that the cost doesn't drift up over time. Adding expectApprox will allow these costs to decrease, but not increase.
