Channel IDs should be carried in frames like Connection IDs

[GrumpyOldTroll]

Connection ID with a required length, e.g. https://www.rfc-editor.org/rfc/rfc9000#name-new_connection_id-frames:

NEW_CONNECTION_ID Frame {
...
  Connection ID (8..160),
...
}

Instead of (i):

MC_CHANNEL_INTEGRITY Frame {
...
  Channel ID (i),
...
}
