py-structlog: updated to 20.1.0

20.1.0

Deprecations:
- This is the last version to support Python 2.7 (including PyPy) and 3.5.
  All following versions will only support Python 3.6 or later.

Changes:
- Added a new module ``structlog.contextvars`` that allows to have a global but \ 
context-local ``structlog`` context the same way as with \ 
``structlog.threadlocal`` since 19.2.0.
- Added a new module ``structlog.testing`` for first class testing support.
  The first entry is the context manager ``capture_logs()`` that allows to make \ 
assertions about structured log calls.
- Added ``structlog.threadlocal.unbind_threadlocal()``.
- The logger created by ``structlog.get_logger()`` is not detected as an \ 
abstract method anymore, when attached to an abstract base class.
- ``colorama`` isn't initialized lazily on Windows anymore because it breaks \ 
rendering.
