Bumps waitress from 1.4.4 to 2.1.1.

Changelog

Sourced from waitress's changelog.

2.1.1

Security Bugfix

- Waitress now validates that chunked encoding extensions are valid, and don't
  contain invalid characters that are not allowed. They are still skipped/not
  processed, but if they contain invalid data we no longer continue in and
  return a 400 Bad Request. This stops potential HTTP desync/HTTP request
  smuggling. Thanks to Zhang Zeyu for reporting this issue. See
  https://github.com/Pylons/waitress/security/advisories/GHSA-4f7p-27jc-3c36


Waitress now validates that the chunk length is only valid hex digits when
parsing chunked encoding, and values such as 0x01 and +01 are no
longer supported. This stops potential HTTP desync/HTTP request smuggling.
Thanks to Zhang Zeyu for reporting this issue. See

Waitress now validates that the Content-Length sent by a remote contains only
digits in accordance with RFC7230 and will return a 400 Bad Request when the
Content-Length header contains invalid data, such as +10 which would
previously get parsed as 10 and accepted. This stops potential HTTP
desync/HTTP request smuggling Thanks to Zhang Zeyu for reporting this issue. See
https://github.com/Pylons/waitress/security/advisories/GHSA-4f7p-27jc-3c36


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.
