      An OSC bundle.
  
      An OSCBundle contains an OSCTimeTag and zero or more OSCBundle Elements.
      The elements of a bundle can be OSC messages or other OSC bundles (this
      means that OSC bundles can be nested).
  
      This is an advanced OSC structure useful to bundle OSC messages together
      whose effects must occur simultaneously at some given time. For most
      use cases it is probably enough to send and receive plain OSC messages.
