BETA - Create a batch of audioforms

BETA: THIS ENDPOINT IS EXPERIMENTAL AND SUBJECT TO CHANGE.

Audioform batches enable the submission of up to 1000 audioforms in a single request. The whole batch is validated as a single unit to catch detectable errors. Once validated, the batch is then processed in parallel. The batch progress can be tracked by via a single batch ID so the user does not need to track 1000s of individual audioform IDs.

Accepts an array of batch items (name + audioform) to be processed in parallel as a batch.
