Porting to pyside6

[orki]

A port for pyside6 is at https://github.com/orki/lucaschessR2/tree/pyside6-porting which I have been using successfully for 2 months on Linux. It is viable for normal use, with a few bugs with the vast majority of functionality working well; the branch should work well for Windows too since nothing OS-specific has been touched, but I don't have Windows to test. It is nowhere near in shape for a PR since my branch makes no attempt whatsoever to maintain pyside2 compatibility.

I'm happy to keep it moving, but I don't think that it is worth writing a compatibility layer to provide both pyside2 and pyside6 compatibility. If you are interested in pyside6, and if you have not already started this work, how would you like to proceed with this branch?

I have made some attempts on my own, initially with problems with the sound, and I have not spent time solving it, because the functionality is the same, unless you tell me otherwise, so I have not continued. I think what it brings is only the future, which is a lot, but there is no rush.
So sooner or later I'll have to make the jump, and your fork will probably save me work as it is.
My current roadmap is to stabilize the program on the current version, without many changes, and maybe open an R6 repository if I have a bug-free pyside6 version.

There is an additional problem and pyside6 does not seem to be compatible with 32-bit versions, which are supported to windows.

The only sound issue I found was a minor incompatibility, which required a straightforward fix. If there are other sound-related issues, I'm not aware of them.
The reason for my port to pyside6 is that pyside2 has not been available in Fedora for a few months and likely other Linux distributions soon since Qt 5.x will no longer support any new releases of python 3. Not sure about others, but this was sufficient impetus for me to build pyside6 and make the necessary changes to LucasChess. When you plan on moving to pyside6, please let me know and I'll be happy to assist.

Hi orki
please, can you update your fork to version R2.14i
