[FEATURE] Schema/API v2.0 implementation phase 3: Create new CLI app for generating new v2 records

[lizkrznarich]

Describe the problem you would like to solve As part of https://github.com/ror-community/ror-roadmap/issues/122, develop a Python CLI app that:

• Accepts ROR record data as a CSV file
• Outputs v2.0 schema-valid ROR records as JSON file(s) stored on the local machine that the app is run on
• Utilizes models/serializers from ror-api to the extent possible. In order to achieve this, the app could be part of ror-api or could import models/serializers as dependencies

Generated records should follow the new v2.0 JSON schema doc and validate successfully using the updated validation-suite

See full specification for details

This app will replace functionality currently in https://github.com/ror-community/leo-form
