Issue #96: ensure the created dimension is sorted

[ank1m]

Github Issue: #96

Description

The order of input files was not preserved in CONCISE. The multi_core_download function was not sorting the returned list from multiprocessing.Manager. So the output order would be random.

Overview of work done

• Added the order number to the input queue for multiprocessing.Manager
• Append the tuple of the order number and output filepath to the multiprocessing output list
• Use the order number to sort the files before the merge step

Overview of verification done

• Built custom concise docker image with the implemented modifications and deployed it in the local harmony environment
• Ran multiple requests and compared the order of datafiles arriving at CONCISE input with the order of datafiles in the output merged file:

Comparison before sorting implemented shows that the order is not preserved	Comparison after sorting implemented shows that the order is preserved

Overview of integration done

See above
