Side Output
-----------

While ParDo always produces a main output PCollection (as the return value from apply), you can
also have your ParDo produce any number of additional output PCollections. If you choose to have
multiple outputs, your ParDo returns all of the output PCollections (including the main output)
bundled together.

**Kata:** Implement additional output to your ParDo for numbers bigger than 100.
