Merge branch 'development' into feature/sra-reporter

* development: (79 commits)
  remove from devDeps
  Remove date for now
  Add ethers typescript typings to 0x.js deps. The library works without this atm since another dep of 0x.js has it as a dep. But it's more robust to have it here.
  Add  missing instructions to add external types to tsconfig.json after installing the package
  Fix bugs in postpublish_utils.js
  Update @0xproject/utils in top-level package.json
  Changelog tweaks
  Publish
  Updated CHANGELOGS
  Fix typo
  Add PR number to changelog entry
  Add changelog update to subproviders package
  Add `numberOfAccounts` param to `LedgerSubprovider` method `getAccountsAsync` and add tests
  Remove unnecessary type assertion
  Fix comments
  Add comments
  Don't need any external packages for 0x connect docs yet
  Instead of adding `@0xproject/types` to tsconfig.json, let's only add it when calling TypeDoc
  Fix styling
  Make prettier ignore postpublish_utils
