[ITP] python-fasteners 0.16.3

[Libor Ukropec]

Hello, I'd like to maintain the python package python-fasteners

This Python standard library provides a lock for threads (both a 
reentrant one, and a non-reentrant one, see below). Fasteners extends 
this, and provides a lock for processes, as well as Reader Writer locks 
for both threads and processes.


This new package is required in order to support more recent version of 
"duplicity" that I adopted.

Please review:

cygport:

build:

This library (in newer version) is also present in LInux distributions, 
e.g. Ubuntu:
https://packages.ubuntu.com/source/focal/s390x/python-fasteners
