Thanks Andy,

Please see https://github.com/apache/arrow/pull/4167#issuecomment-543381089
for the status of the PR. We have a few missing data types (fixed list,
timezone to timestamp, etc.) that are currently stopping me from testing
the reading of files.

I'm trying out creating a fixed size list, and I'll open a PR for that if
my attempt works.
