[PR] [PYTHON] Add a recipe for sending mixed schema data over a single Flight stream [arrow-cookbook]

["nph (via GitHub)" <gi...@apache.org>]

nph opened a new pull request, #353:
URL: https://github.com/apache/arrow-cookbook/pull/353

   
   Recently there was a [question](https://lists.apache.org/thread/xwxskb7mnfsc6qsoxgsk2yr38shyxrvw) on the Arrow Users mailing list about how to send tables or record batches with multiple schemas over a single Flight stream. @lidavidm provided a helpful answer and mentioned that this question had come up in discussion [previously](https://lists.apache.org/thread/5lzxx5onmvq9w7vdrnxjt3vt4t66dczz). I thought the suggested solution would be a good addition to the cookbook since the idea of using a union of struct types may not be entirely obvious to newcomers to Flight and the problem itself is one that multiple people have run into (including me :-)
   
   Anyway here's my attempt at a recipe. Any feedback gratefully appreciated.

   This is perhaps not really Flight specific but it works here.
   
   There's a separate PR to upgrade the PyArrow version, @amoeba should that go in first?
