python-attrs update

[Antonio Valentino <antonio.valentino@tiscali.it>]

Dear all,
I have prepare an updated version of the package python-atts.
The code is in my fork on salsa:
https://salsa.debian.org/antonio.valentino/python-attrs

I have also created a merge request on salsa:
https://salsa.debian.org/python-team/packages/python-attrs/-/merge_requests/2

The latest upstream version of python-attrs is needed by a new package 
(sarsen) that I'm working on. It will be include in Debian GIS.

I kindly ask to someone in debian-python to review the changes and 
upload the new version of the package.

kind regards
