Remove Tools/pynche

[warsaw]

@larryhastings reminded me of this ancient program. It's way past time to remove this directory from Tools/. I have no way to test it and zero interest in supporting it. I don't even know the last time anybody mentioned it. I don't even have enough interest to keep it alive in a separate repository.

Fun historical fact: I wrote the original version of this color editor for SunView.

I see this tool as a neat way to find some pretty named color. Maybe it should be moved to Tools/demo as an example of how to use TKInter in a real (multifile) program? I can reorganize the tool's code to make it testable if it's viable.

A patch to make a program runnable:

diff --git a/Tools/pynche/PyncheWidget.py b/Tools/pynche/PyncheWidget.py

I runned it as follows:

JFY: I'm trying it out in https://github.com/python/cpython/compare/main...arhadthedev:dustoff-pynche?expand=1.

@arhadthedev if you're interested in maintaining it, probably better to just start a new repo. That way there's one less thing to keep around in Python itself.

I wouldn't be opposed to either option. I can think of a couple of choices:

1. Move it to a separate repository in the python org
2. Create a new project outside the python org and set up some contributors
3. Delete it as planned above

If I was to do it, I'd prefer GitLab, but GitHub is just fine too. Preferences?

I see no reason to keep this buried within the CPython repo.. Delete it here. Let whoever wants to maintain it put it up in a new repo anywhere (and presumably on pypi - their choice).

LOL SunView!

[warsaw]

Okay, I will copy the files out into my own repo (likely on GitLab though), and will happily add any contributors who want to help out. I'm going to mark this PR as draft until then, then will undraft it and merge. Thanks!

You may know it already but in case not, here are some magic git commands to copy files into a new repo, preserving history:

Before this tool has been removed, I didn't know it! It's interesting that it still works (with a oneliner patch)! I didn't know SunOS SunView neither!

Tool added to Python in 1998 (Python v1.5.1) with commit 516f189:
