Radio buttons should not be deselectable

[jamesrussell216]

In the Acquisition window, you can click on a selected Mode radio button and have no select radio options!

This is the result of this change nion-software/nionui-tool@67c5dec. I am reviewing why that change was needed.

This is fixed nion-software/nionui-tool@419509e and f378ed7

However, I am not 100% confident about the fix - I had disabled a setting for "autoExclusive" (auto disables other buttons belonging to a common parent) on the Qt radio buttons in May 2021, but I couldn't find any case where it fails now without "autoExclusive" disabled. So I re-enabled it and that fixes this particular issue. As a fallback, I included a way to set the "autoExclusive" setting from Python in the future if needed.

General point is that Declarative should auto-create a radio group to fully resolve this issue. The problem with doing that is where to store the button group... I'll leave that as an exercise for another day.

Watch for other radio button issues now that I've re-enabled "autoExclusive". Possible issue would be wrong item selected even though the correct radio button is enabled.

Sorry @cmeyer but still seems to be possible unless I'm missing something...

To test this, you either need to run Swift using PyQtProxy (latest code) or using a newly built nionui-tool. Are you still seeing the error in one/both of those situations? More details on launching with nionui-tool here.

@cmeyer I thought so but @KRLango then found...

Is that going to be why?!

Did you run the Windows version from that link? The linux and macos builds are failing, but the Windows build looks successful. (I'm working on those builds separately)
