default Tensor map(DoubleUnaryOperator mapper) {
        return new com.yahoo.tensor.functions.Map<>(new ConstantTensor<>(this), mapper).evaluate();
    }
Returns a new tensor where existing cells in this tensor have been
removed according to the given set of addresses. Only valid for mapped
or mixed tensors. For mixed tensors, addresses are assumed to only
contain the mapped dimensions, as the entire indexed subspace is removed.

@param addresses list of addresses to remove
@return a new tensor where cells have been removed
