We had to perform a small re-write of master. The commits may look a bit odd, but it should not cause conflicts. Could you kindly rebase this against the latest master to make it easier to review? |

Provide support for serializing dictionary arrays to CSV and JSON by hydrating them to their underlying representation. This is not the most efficient way to do this, but was the simplest way I could think of to cover all bases.
It may be worthwhile special-casing StringDictionaries with a more efficient implementation in a subsequent PR, as I imagine they're the most common form of DictionaryArray.
