0.6.0

Welcome to nostrum 0.6.0, bringing you message content intents, API v10, voice
improvements, new permissions, and more!

A huge thanks to @Th3-M4jor, @BrandtHill and @daskycodes for their contributions
to this release!

Breaking changes

• If your bot relies on message content, you will need to add :message_content
  in your :gateway_intents configuration setting.
• Voice listening now automatically parses RTP and Opus. You can pass false as
  the third argument to listen/2-3 to reuse the previous behaviour.
• The :manage_emojis permission was renamed to :manage_emojis_and_stickers
