feat: plate navigator for HCS calibration testing

[fdrgsp]

@tlambert03 what do you think to use something like this for the calibration testing of the HCS wizard? Basically the user has the freedom to click anywhere in the well to move to the stage...

love it. we certainly need something like that. When you click does it always go to the center? something that some commercial software add is the ability to go to top/left/bot/right/center:

(or, in the corners for a square well). If you're trying to calibrate a plate, those would likely be more useful places to visit? of course, as the number of wells goes up, it would be hard to show all of those points

When you click does it always go to the center?

At the moment, the stage goes wherever you click in the well (not always in the center). But we can make fixed position per well I guess!

ah! i see, yeah that's cool too. i can imagine two different modes i guess. one where you likely want specific easily identifiable places, and the current one with complete freedom

woah that's gorgeous

@tlambert03 I think this widget is functioning as we want, when you have time can you have a look at the code?

Once this is merged, I can open a PR where we combine it with the PlateCalibrationWidget.
