[dependabot]

Bumps waitress from 2.0.0 to 2.1.0.

Changelog

Sourced from waitress's changelog.

2.1.0

Python Version Support

- Python 3.6 is no longer supported by Waitress

Python 3.10 is fully supported by Waitress

Bugfix

- ``wsgi.file_wrapper`` now sets the ``seekable``, ``seek``, and ``tell``
  attributes from the underlying file if the underlying file is seekable. This
  allows WSGI middleware to implement things like range requests for example
See Pylons/waitress#359 and

Pylons/waitress#363


In Python 3 OSError is no longer subscriptable, this caused failures on

Windows attempting to loop to find an socket that would work for use in the

trigger.
See Bugfix on Windows: OSError is not subscriptable Pylons/waitress#361


Fixed an issue whereby BytesIO objects were not properly closed, and

thereby would not get cleaned up until garbage collection would get around to

it.
This led to potential for random memory spikes/memory issues, see

Close old buffer when overflowing in OverflowableBuffer Pylons/waitress#358 and

Memory/Resource leak Pylons/waitress#357 .
With thanks to Florian Schulze for testing/vaidating this fix!


Features




When the WSGI app starts sending data to the output buffer, we now attempt to
send data directly to the socket. This avoids needing to wake up the main
thread to start sending data. Allowing faster transmission of the first byte.
See Pylons/waitress#364
With thanks to Michael Merickel for being a great rubber ducky!


Add REQUEST_URI to the WSGI environment.
REQUEST_URI is similar to request_uri in nginx. It is a string that
contains the request path before separating the query string and
