%%% @doc Factory supervisor for `macula_feeder' children.
%%%
%%% Meant to be embedded in the caller's own supervision tree: the
%%% application decides when to start a new feed and when to cancel one
%%% via `supervisor:terminate_child/2' (or `macula_feeder:cancel/1' on
%%% the child pid directly). Children are `temporary' — a finished or
%%% crashed feed is never restarted.
