Bulk Create Evaluation Set Items

If you have a large number of files that you need to add to an evaluation set, you can use this endpoint to create multiple evaluation set items at once. This can be useful if you have a large dataset that you need to evaluate the performance of a processor against.

Note: you still need to create each File first using the file API.
