python3-tornado: Upgrade 6.0.4 -> 6.1

Upgrade to release 6.1:

- Windows support has been improved. Tornado is now compatible
  with the proactor event loop (which became the default in Python
  3.8) by automatically falling back to running a selector in a
  second thread. This means that it is no longer necessary to
  explicitly configure a selector event loop, although doing so
  may improve performance. This does not change the fact that
  Tornado is significantly less scalable on Windows than on other
  platforms.
- Binary wheels are now provided for Windows, MacOS, and Linux
  (amd64 and arm64).
- This is the last release of Tornado to support Python 3.5.
  Future versions will require Python 3.6 or newer
