[FEATURE] API v2: Bulk record create/update from CSV endpoint

[lizkrznarich]

Describe the problem you would like to solve As part of https://github.com/ror-community/ror-roadmap/issues/122, add API functionality to ROR API that supports generating new or updated record files in bulk using data submitted to the API in a CSV file.

Describe the solution you'd like Functionality should behave as follows:

1. User submits a CSV file to API endpoint with field values specified in columns identified by column headings.

• ROR ID column should be empty for new records and populated for existing records.
• For updated records, only new/updated fields and ROR ID field must contain values
• Fields values can be deleted by including the field name and setting its value to “delete”

2. For each row, new or updated record steps above are completed using create and update functionality described in https://github.com/ror-community/ror-roadmap/issues/204 and https://github.com/ror-community/ror-roadmap/issues/205. If an error occurs, the row is skipped and an error message is appended to the response.
3. API returns a ZIP file object containing generated records for all successful rows. If any (or all) rows were skipped due to errors, API returns an error message containing the full list of errors.

Who would benefit from this feature? ROR curation team
