NAMESPACE_DONE — MoQT draft-16 §9.23.

The publisher sends the NAMESPACE_DONE control message to indicate its intent to stop serving new subscriptions for tracks within the provided Track Namespace. All NAMESPACE_DONE messages are in response to a SUBSCRIBE_NAMESPACE, so only the namespace tuples after the 'Track Namespace Prefix' are included in the 'Track Namespace Suffix'.

NAMESPACE_DONE Message {
  Type (i) = 0xE,
  Length (16),
  Track Namespace Suffix (..)
}
