build(deps): Bump structlog from 19.2.0 to 20.1.0 in /tools

[dependabot-preview]

Bumps structlog from 19.2.0 to 20.1.0.

Changelog

Sourced from structlog's changelog.

20.1.0 (2020-01-28)

Backward-incompatible changes:

none

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. #201, #236
• 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. #14, #234
• Added structlog.threadlocal.unbind_threadlocal(). #239
• The logger created by structlog.get_logger() is not detected as an abstract method anymore, when attached to an abstract base class. #229
• colorama isn't initialized lazily on Windows anymore because it breaks rendering. #232, #242
