Bug#1042459: move python3-doit to Debian Python Team to upgrade to latest version

[Drew Parsons <dparsons@debian.org>]

Source: doit
Version: 0.31.1-3.4
Followup-For: Bug #1042459
X-Debbugs-Cc: debian-python@lists.debian.org, Agustin Henze <tin@debian.org>, Iñaki Malerba <inaki@malerba.space>

The Debian maintainers of python package doit seem to be MIA,
with no upload since 2019.

I'd therefore like to move the doit package over to the Debian Python
Team, including moving the salsa repo.

A new version of doit is required in order to build the latest version
of scipy.

Thanks,
Drew
