gather

def gather[dtype: DType, indices_type: DType, //, *, axis: Int, target: StringSlice[StaticConstantOrigin] = StringSlice("cpu")](output: TileTensor[dtype, address_space=output.address_space, linear_idx_type=output.linear_idx_type, element_size=output.element_size], input: TileTensor[dtype, address_space=input.address_space, linear_idx_type=input.linear_idx_type, element_size=input.element_size], indices: TileTensor[indices_type, address_space=indices.address_space, linear_idx_type=indices.linear_idx_type, element_size=indices.element_size], *, context: DeviceContext)

Gather operation as defined in https://github.com/onnx/onnx/blob/main/docs/Operators.md#Gather.

Note that this is NOT the same as the default PyTorch gather (which is equivalent to https://github.com/onnx/onnx/blob/main/docs/Operators.md#gatherelements).
