Packaging Niffler with pip

[pradeeban]

This is slightly tricky since Niffler is not just Python.

Among the modules, the below are in Python:

• cold-extraction
• dicom-anonymization
• meta-extraction
• nifti-extraction
• png-extraction
• rta-extraction
• suvpar

Although the above could be packaged with pip following [1], there are complex dependencies such as DCM4CHE as storescp for cold-extraction and meta-extraction, mongo for meta-extraction, and gdcm for png-extraction. Additional care must be taken on initiatives on packaging Niffler as an installable configuration to ensure this is complete.
