With this PR, I make --headless mode handle a special case: a workflow of "open file -> multi-channel network prediction -> export file". A workflow combined with any post-processing step may still fail. Multi-channel output from networks were not handled until #184. Back then, --headless mode with DAG was not considered as an important use case, because
I made --config mode available for processing multi-channel network output;
