Input PEP for Looper vs output PEP given to Pipestat

Related to this Pipestat enhancement: https://github.com/pepkit/pipestat/issues/125

Can Looper easily distinguish between using an input pep and sending an output pep for results reporting via pipestat?

Pipestat now has the pephub_path parameter: psm = PipestatManager(pephub_path=pephuburl, schema_path=schema_file_path)

But it does not search for this via a config file (yet), so Looper may not be able to send this information to Pipestat at this time.

Previous discussion: we decided it best to keep the input PEP separate from the output PEP.
