A composable workflow module

[pradeeban]

Currently, the processes are scheduled manually or the workflows are developed manually per each execution. This workflow module will enable chaining of processes:

One common workflow is, cold-extraction -> png-extraction, which will retrieve the images and then convert the DICOM images to PNG images and extract metadata.

Another workflow we use is for scanner utilization. It is, cold-extraction -> png-extraction -> scanner-util.

The aim is to reduce human-in-the-loop in several repeated execution patterns we have.

Integrated Modality Splitting, PNG Extraction, DICOM Anonymization, and Metadata Anonymization. But Cold Extraction is not working in the workflows.
