Programmable Chat v5.0.0 (May 17, 2021)

Breaking changes:

Major internals improvement (the "Sessionless" protocol)
This improvement is designed primarily for improved reliability. While this is not a breaking code change, it does carry a meaningful impact on timing:
- SDK commands will return success or failure up to ~10% more quickly than before.
- Real-time updates of data is now likely to arrive after the command completes.
  For example, Channel.updateAttributes() will resolve successfully while Channel#attributes still contains the old value. To see the new value, we recommend waiting for an #updated event.
Passing null to Channel.sendMessage will result with the message body being an empty string.
User.updateFriendlyName no longer accepts null as the value.
Channel.updateFriendlyName no longer accepts null as the value.
