Anaconda worker doesn't start due to asyncore and asynchat missing

[RenHoekNL]

I installed the latest Python version (python-3.12.0-amd64.exe) today and installed the package. It complained that the worker isn't running.

I tried starting the worker by hand to see what's going on:

cd "%appdata%\Sublime Text 3\Packages\Anaconda"
python -B anaconda_server/jsonserver.py -p test 9999 DEBUG

I got the following errors:

• ModuleNotFoundError: No module named 'asyncore'
• ModuleNotFoundError: No module named 'asynchat'

Which could be solved by

python -m pip install pyasyncore
python -m pip install pyasynchat

Turns out that asyncore and asynchat (ref:https://pypi.org/project/pyasynchat/) are no longer part of the standard modules.

I had to do the following since these packages arent managed in homebrew

python -m pip install pyasynchat --break-system-packages &&
python -m pip install pyasyncore --break-system-packages

I also had to do this wbond/package_control#1612 (comment)
in order to get Sublime Package manager working again

Based on Python docs, asyncore that Anaconda depends on

anaconda/anaconda_server/jsonserver.py

Line 13 in 2cb208d

import asyncore

got removed from Python 3.12

Deprecated since version 3.6, will be removed in version 3.12: The [asyncore](https://docs.python.org/3.11/library/asyncore.html#module-asyncore) module is deprecated (see [PEP 594](https://peps.python.org/pep-0594/#asyncore) for details). Please use [asyncio](https://docs.python.org/3.11/library/asyncio.html#module-asyncio) instead.
