[lizkrznarich]

Describe the problem you would like to solve As part of https://github.com/ror-community/ror-roadmap/issues/122, develop Python script(s) that can:

• Crosswalk 1 or more individual ROR records from schema v2.0 to 1.0
• Crosswalk an entire ROR data dump from schema v2.0 to 1.0

Records crosswalked to v2.0 should follow the https://github.com/ror-community/ror-roadmap/issues/164 and validate successfully using the https://github.com/ror-community/ror-roadmap/issues/165
