Endpoint to manage regions with the additional /batch/ action to create a batch of regions asynchronously.

When used in /batch/ mode, the endpoint endpoint will create regions in the given order in the payload's list, meaning that the order of regions is important. Any parent region must already exist by the time a region is created. If a child region appears before its parent is created, it will be ignored.

Returns: id: A Job ID.

Example: Input: [ {"name": "Region1", "center_position_latitude": "", ...}, {"name": "Region2", "center_position_latitude": "", ...}, ]
