Community Catalog: add special compensators for Projects Script

[shaunanoordin]

PR Overview

Part of: Community Catalog

This PR adds "special compensators" for the Projects Script - i.e. rules that smooth out unplanned wonkiness in actual data.

• New compensator: ignore upper/lower case in metadata fields.
  • Some projects (e.g. Stereovision) don't have consistent metadata fields across Subjects. For example, Subject 1 might have subject.metadata.file_name, while Subject 2 might have subject.metadata.File_Name.
  • This compensator ensures both metadata fields count as "file_name" (or whatever our config asks for)
  • Config: myProject.special_compensators. metadata_field_name_ignore_case = true | false (default: false)

While ideally we would like the actual Subject data in Panoptes to be consistent, we understand that unplanned wonkiness is just a natural facet of the human experience, so the code should try its best to compensate.
