py-structlog: updated to 21.2.0

21.2.0 (2021-10-12)
-------------------

Backward-incompatible changes:

- To implement pretty exceptions (see Changes below), \ 
``structlog.dev.ConsoleRenderer`` now formats exceptions itself.

  Make sure to remove ``format_exc_info`` from your processor chain if you \ 
configure ``structlog`` manually.
  This change is not really breaking, because the old use-case will keep working \ 
as before.
  However if you pass ``pretty_exceptions=True`` (which is the default if either \ 
``rich`` or ``better-exceptions`` is installed), a warning will be raised and \ 
the exception will be renderered without prettyfication.

Changes:

- ``structlog`` is now importable if ``sys.stdout`` is ``None`` (e.g. when \ 
running using ``pythonw``).
- ``structlog.threadlocal.get_threadlocal()`` and \ 
``structlog.contextvars.get_contextvars()`` can now be used to get a copy of the \ 
current thread-local/context-local context that has been bound using \ 
``structlog.threadlocal.bind_threadlocal()`` and \ 
``structlog.contextvars.bind_contextvars()``.
- ``structlog.threadlocal.get_merged_threadlocal(bl)`` and \ 
``structlog.contextvars.get_merged_contextvars(bl)`` do the same, but also merge \ 
the context from a bound logger *bl*.
  Same pull requests as previous change.
- ``structlog.contextvars.bind_contextvars()`` now returns a mapping of keys to \ 
``contextvars.Token``\s, allowing you to reset values using the new \ 
``structlog.contextvars.reset_contextvars()``.
- Exception rendering in ``structlog.dev.ConsoleLogger`` is now configurable \ 
using the ``exception_formatter`` setting.
  If either the `rich <https://github.com/willmcgugan/rich>`_ or the \ 
`better-exceptions <https://github.com/qix-/better-exceptions>`_ package \ 
is present, ``structlog`` will use them for pretty-printing tracebacks.
  ``rich`` takes precedence over ``better-exceptions`` if both are present.

  This only works if ``format_exc_info`` is **absent** in the processor chain.
- All use of ``colorama`` on non-Windows systems has been excised.
  Thus, colors are now enabled by default in ``structlog.dev.ConsoleRenderer`` \ 
on non-Windows systems.
  You can keep using ``colorama`` to customize colors, of course.
- The final processor can now return a ``bytearray`` (additionally to ``str`` \ 
and ``bytes``).
