Bumps waitress from 1.3.0 to 1.4.2.

Changelog

Sourced from waitress's changelog.

1.4.2 (2020-01-02)

Security Fixes


- This is a follow-up to the fix introduced in 1.4.1 to tighten up the way
  Waitress strips whitespace from header values. This makes sure Waitress won't
  accidentally treat non-printable characters as whitespace and lead to a
  potental HTTP request smuggling/splitting security issue.

  Thanks to ZeddYu Lu for the extra test cases.

  that was published for RFC7230.
