v2.2.0 available as Beta

[Peter Falkingham]

Hello Everyone,

  v2.2.0 is now available for beta testing:

https://github.com/XROMMPackages/xmalab/releases/tag/v2.2.0 

  I could do with some users to test it out and see if anything breaks. It _should_ behave as before, but I can't guarantee that because I don't have time for exhaustive testing, so don't use it for anything important yet.

User-facing Changes:

 - New look! Slightly different theme, and you can now enable light mode or dark mode (or follow system).  This doesn't persist if you close and open it again, despite my best efforts, but I'm looking into it.

 - Undistortion and Marker tracking should be a [tiny] bit quicker.  Particularly marker tracking which has been slower on Windows since v1.5.5.  Let me know how you get on here, and if there's any tangible difference.

 - All links on help/about/welcome have been updated to point to our new github (https://github.com/XROMMPackages), including code, scripts, and wikis.

Changes under the hood:
 - Updated libraries, including big changes resulting from moving from QT5.15 to QT6.9.  I'd hoped that would fix the missing file picker dialogue issues on MacOS Sequoia and later, but it didn't, so that was several days well spent. However...

 - all file picker dialogues fixed now (with a global out to use non-native file pickers on MacOS.  You won't notice the difference).

Please try it out (on a copy of your data!) and let me know how you get on.
