The Python Slack client [added a `SignatureVerifier` class](https://github.com/slackapi/python-slackclient/pull/686) in version `2.6.0`. If possible, we should update our [Slack GCF sample](https://github.com/GoogleCloudPlatform/python-docs-samples/blob/master/functions/slack/main.py) to use this instead of [manually validating message signatures](https://github.com/GoogleCloudPlatform/python-docs-samples/blob/master/functions/slack/main.py#L33-L45).
