Pull Request

Purpose

Fixes SyntaxWarning thrown by python 3.12, update sync up nzbget from updates from sab version

Approach

Script now generates SyntaxWarning on python 3.12+

python3.12 changes:

A backslash-character pair that is not a valid escape sequence now generates a SyntaxWarning, instead of DeprecationWarning. For example, re.compile("\d+\.\d+") now emits a SyntaxWarning ("\d" is an invalid escape sequence, use raw strings for regular expression: re.compile(r"\d+\.\d+")). In a future Python version, SyntaxError will eventually be raised, instead of SyntaxWarning. (Contributed by Victor Stinner in gh-98401.)
