In order to add BagIt bags to APTrust, we will create an APTrust BagIt Profile for fcrepo-import-export.
Definition of done is conformance to the following document: https://docs.google.com/document/d/1F9ssL6-N2Yum5E1EsMyb_H92lDVRLhrLBEDB19PAfqE/edit#heading=h.nbx73mq7699
N.B. fcrepo-import-export need not run the APTrust bag validation script.
- Might need to explore bag sequences to adhere to the 250GB limit
