py-waitress: updated to 1.2.1

1.2.1:

Bugfixes
- When given an IPv6 address in X-Forwarded-For or Forwarded for=
  waitress was placing the IP address in REMOTE_ADDR with brackets:
  [2001:db8::0], this does not match the requirements in the CGI spec which
  REMOTE_ADDR was lifted from. Waitress will now place the bare IPv6
  address in REMOTE_ADDR: 2001:db8::0.
