Hi!

A new version was just released of @slack/client, so Doppins has upgraded your project's dependency ranges.

Make sure that it doesn't break anything, and happy merging! :shipit:

Upgraded @slack/client from 3.2.0 to 3.3.0

Changelog:

Version 3.3.0

• Creates a memory data store by default if an undefined, but not false|null value is passed for opts.dataStore
• Aliases the retry policies to be human readable

  Version 3.2.1

• Updates the RTM client to emit an UNABLE_TO_RTM_START event when all reconnection attempts are exhausted, rather than throwing an error
• Suppresses some spurious log lines when tests are run

An additional new version was just released of @slack/client, so we've added an extra commit upgrading your range to 3.4.0.

Hope that's alright! — Doppins
