Transform a synchronous Iterable of arbitrary JavaScript values into a
sequence of Arrow Vector following the chunking semantics defined in
the supplied options argument.
This function returns a function that accepts an Iterable of values to
transform. When called, this function returns an Iterator of Vector<T>.
The resulting Iterator<Vector<T>> yields Vectors based on the
queueingStrategy and highWaterMark specified in the options argument.
If queueingStrategy is "count" (or omitted), The Iterator<Vector<T>>
will flush the underlying Builder (and yield a new Vector<T>) once the
Builder's length reaches or exceeds the supplied highWaterMark.
If queueingStrategy is "bytes", the Iterator<Vector<T>> will flush
the underlying Builder (and yield a new Vector<T>) once its byteLength
reaches or exceeds the supplied highWaterMark.
