Can't run v4.3.2 on Slackware64-15.0

[Tonus1]

Hi,

I'm having trouble to get the lastest version of todoman (4.3.2 atm) run on fully upgraded Slackware64-15.0
Seems to be related to uncompatible python version : here python v3.9.18 and setuptools-65.1.1 (do not build with stock 57.5.0).

Build and runtime deps are

python3-atomicwrites click click-log icalendar python3-dateutil parsedatetime humanize python3-tabulate python-urwid pytz

The error seems related to this syntax in widget.py (commit b08318a) and cli.py (line 100, commit 17dc309)

def __init__(self, parent: urwid.Widget, *a, **kw) -> None:

Reverting all the related syntax to something like this works

def __init__(self, parent, *a, **kw):

Since I'm total noob in python there's surely a better solution.

Edit : forgot to past the error !

Right, the syntax of our annotations is not compatible with Python 3.9. 16a4983 should fix this.
