Enhancement: Symbolic links to ORIGINAL_DATA for DATA when publishing

[astrochun]

Summary

For preservation, we need to have the files in DATA. Thus, when the move_publish is executed, it should create symbolic links if such files do not exist in DATA. This might require some checking against Figshare when it's published.

Objectives

Symbolic links for all data files should be present in DATA.

Proposal

There are two parts for this feature:

• Implementing it a part of move_publish alias, which calls the perform_move script with --direction publication. This is for future curated datasets.
• Implement it as part of the preserve_checks script (see Feature: Python script and module to check dataset readiness for data preservation #235), which is used for datasets that are published already.
