Constructs a cell union with the given S2CellIds, then calls Normalize()
to sort them, remove duplicates, and merge cells when possible. (See
FromNormalized if your vector is already normalized.)
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().
A cell union containing a single S2CellId may be constructed like this:
