Operation: Remove use of Inheritance Principle

[Lestropie]

For a given input BIDS dataset, remove all uses of the Inheritance Principle.
Collapse all metadata to be defined exclusively in sidecar files alongside data files.

This should be a relatively simple operation:

• For every data file in the input BIDS dataset:
  • Copy the data file to the same location in the output BIDS dataset
  • For all metadata files deemed to be applicable to the data file based on the Inheritance Principle:
    • Load metadata into a dictionary
      (obeying the Inheritance Principle in terms of the order in which those files should be read in order for overloaded values to be properly obeyed)
  • Write sidecar metadata file to accompany data file
