Fixes https://issues.apache.org/jira/browse/ARROW-3336. Realized too late I branched from the https://github.com/apache/arrow/pull/2616, so that's why there's some extra commits at the front.
Check out the relevant tests here: https://github.com/trxcllnt/arrow/blob/860f61046fca0081dbe0ce986a97408ed5934e22/js/test/unit/writer-tests.ts#L26. This test covers the primitive, nested, and dictionary vectors, but it'd be worth adding more (for example, Unions).
