python-tornado: update to version 6.0.4

General changes
~~~~~~~~~~~~~~~

- Binary wheels are now available for Python 3.8 on Windows. Note that it is
  still necessary to use
  ``asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())`` for
  this platform/version.

Bug fixes
~~~~~~~~~

- Fixed an issue in `.IOStream` (introduced in 6.0.0) that resulted in
  ``StreamClosedError`` being incorrectly raised if a stream is closed mid-read
  but there is enough buffered data to satisfy the read.
- `.AnyThreadEventLoopPolicy` now always uses the selector event loop on Windows.
