Would it be possible to add the deployment of token pricer contracts into the SDK?

For now, we have coded the deployment ourselves in internal tooling, for example for TradeTracker:

import { ContractFactory } from 'ethers'
const TRADE_TRACKER_ABI = [{"type":"constructor","inputs" ...
const TRADE_TRACKER_BYTECODE = "0x60e060 ...
  const TradeTrackerFactory = new ContractFactory(
    TRADE_TRACKER_ABI,
    TRADE_TRACKER_BYTECODE,
    chainDeployerSigner
  );
  const contract = await TradeTrackerFactory.deploy(
      decimals,
      40,
      sequencerInbox
  );
  const deployedContract = await contract.deployed();
