Python 3.11 compatibility

[CyrilleB79]

This PR fixes issues with this add-on when run with Python 3.11 (last alpha).

Issues

1. An error in the add-on update system:

ERROR - globalPluginHandler.initialize (11:18:49.285) - MainThread (17360):
Error initializing global plugin <class 'globalPlugins.ibmtts.GlobalPlugin'>
Traceback (most recent call last):
  File "globalPluginHandler.py", line 32, in initialize

    self.timer.Start(self.millis, wx.TIMER_ONE_SHOT)
TypeError: Timer.Start(): argument 1 has unexpected type 'float'

2. A deprecation warning from Python 3.11

   DEBUGWARNING - Python warning (11:17:13.460) - MainThread (3284):
   C:\Users\Cyrille\AppData\Roaming\nvda\addons\IBMTTS\synthDrivers\_ibmeci.py:377: DeprecationWarning: setDaemon() is deprecated, set the daemon attribute instead
   self.setDaemon(True)

Solutions

1. Since an integer value is now required for core.callLater, convert the value to int.
2. Use the daemon attribute as requested.

Note

To ensure continuity of automatic update, it's important to release a version of this add-on with the update system fixed before people are able to upgrade to NVDA 2024.1 (or even better before 2024.1beta1)

Hi @CyrilleB79, I need to update a lot of things of my add-ons, I've been in no good personal situations and I had to prioritize my fundamental activities. Thank you for the contributions. About this PR, I would prefer to preserve compatibility with older versions of NVDA, so, I will look for a solution that can work from the NVDA 2019.3 to 2024.1. In the future, I will remove the compatibility code, but for now, I think is not a good idea to stop supporting older NVDA versions.

@davidacm, to clarify: This PR makes the add-on compatible with NVDA Python 3.11 alpha versions, but it does not break the compatibility with Python 3.7:

• Point 1 is just a conversion to "int", so no compa issue.
• Point 2 uses the daemon attribute of Thread, and this attribute is already present on Python 3.7.

I have run NVDA 2019.3 with this version of the add-on and it is working well.
