        Do a cutout and return the unique ids within the specified region.

        0 is never returned as an id.

        Args:
            cutout_fcn (function): SpatialDB's cutout method.  Provided for naive search of ids in sub-regions
            resource (project.BossResource): Data model info based on the request or target resource
            resolution (int): the resolution level
            corner ((int, int, int)): xyz location of the corner of the region
            extent ((int, int, int)): xyz extents of the region
            t_range (optional[list[int]]): time range, defaults to [0, 1]
            version (optional[int]): Reserved for future use.  Defaults to 0

        Returns:
            (numpy.array): unique ids in a numpy array.
