Timeboost mode for nitro-testnode

This PR adds support for timeboost mode on nitro-testnode. It starts the bid-validator, autonomous auctioneer, deploys the ExpressLaneAuction contract, and starts the sequencer in Timeboost mode.

Since Timeboost is not yet merged into the main nitro or contracts branches, currently you will need to follow the following steps to run nitro-testnode in Timeboost mode. (This will improve once things are merged in.)

checkout nitro, branch: express-lane-timeboost
In the nitro dir, go into the contracts submodule and check out express-lane-auction-all-merged
- run yarn build:all inside this directory
Edit scripts/config.ts function "writeL2ChainConfig", and change "InitialArbOSVersion" to 31. (This will be fixed soon as nitro and contracts are merged.)
In the nitro dir, go into the nitro-testnode submodule and check out timeboost-mode
- From this directory, run DEFAULT_NITRO_CONTRACTS_VERSION=99c07a7db2fcce75b751c5a2bd4936e898cda065 ./test-node.bash --init-force --dev --dev-contracts --l2-timeboost

When starting up, look for the line printing the token and contract address:

== Bidding token: $biddingTokenAddress, auction contract $auctionContractAddress

You can also find the auction contract and auctioneer address with the following command.

$ docker compose run --entrypoint sh sequencer -c "cat /config/sequencer_config.json" | jq .execution.sequencer
 ✔ Container nitro-testnode-geth-1  Running0.0s 
{
  "enable": true,
  "timeboost": {
    "enable": true,
    "auction-contract-address": "0x7DD3F2a3fAeF3B9F2364c335163244D3388Feb83",
    "auctioneer-address": "0x46225F4cee2b4A1d506C7f894bb3dAeB21BF1596"
  }
}

Users alice and bob have been pre-funded with some of the bidding token on L2 and can be used right away.

$ docker compose run scripts print-private-key --account user_alice

$ docker compose run scripts print-private-key --account user_bob

# make a deposit into the ExpressLaneAuction contract

# make a bid for control of the next express lane round

Commands for sending express lane transactions will be provided in future, see implementation and spec .
