py-structlog: updated to 18.2.0

18.2.0:

Changes:
- Added structlog.stdlib.add_log_level_number() processor that adds the level \ 
*number* to the event dictionary.
  Can be used to simplify log filtering.
- structlog.processors.JSONRenderer now allows for overwriting the *default* \ 
argument of its serializer.
- Added try_unbind() that works like unbind() but doesn't raise a KeyError if \ 
one of the keys is missing.
