Constructs a cell union from S2CellIds that have already been normalized (typically because they were extracted from another S2CellUnion).
The argument is passed by value, so if you are passing a named variable and have no further use for it, consider using std::move().
REQUIRES: "cell_ids" satisfies the requirements of IsNormalized().
