C1c-4: the tool runner sends a bundle's chunked seat answer in chunks, and a node's chunked verb is asked of the node

Browse Source 
A seat verb whose definition says chunks, served by a bundle that answers the whole file as the member `file`, is sent by the
runner with buscalls.SeatChunks.Send and answered with the chunk count (Conn.AnswerChunked, called from serveSeats). A chunked verb
asked of one machine (`@<node>`) is received in chunks as the verb is.

Builds: design 47 G A-257, A-249, A-254, §681
