support for Qt 6 builds

[3nids]

This makes the plugin compatible with Qt6 builds.

QGIS minimum version is raised to 3.34, the config dialogs is shown only for 3.40+.

Another approach would be to set the new minimum version to 3.40 (so we would leave the old version for 3.34-3.38), no strong opinion here.

(The test is failing because the new API from recent commits has not yet reached the docker image)

There are some things going on that I cannot completely grasp (not enough experience handling settings from QGIS), but in general it looks good to me. 👍🏽

I'll test in GUI and let you know if I find anything strange.

It seems that objectis not necessary for Python 3. It was a Python 2 thing.

This one looks a bit better to me, but I guess there are pros and cons for both options.
In February 2025, 3.40 will be LTR anyways.

For reference, followup #92

Thanks a lot for the review.

There's one scenario I'm a bit worried about raising to 3.40.
Let's say someone has both versions used with the same profile: you upgrade Swiss Locator when you open 3.40, it becomes unusable when you open 3.34.

Another point to take into account is how important it is to push new releases to 3.34:

• with the min 3.34 approach, it's included
• with the min 3.40 approach, we need to have a separate branch

let's bump to 3.40 and we can revert to 3.34 if needed later on!

Yeah, good points. You know more about pros and cons with respect to the user base, let's hope it works with 3.40 as min and if not we need to be ready to revert as you said. 👍🏽
