Create TunableLabel for interactive frequency tuning

[aa5sh]

Introduces the TunableLabel custom widget, enabling mouse wheel and click-based frequency adjustments in RigWidget. RigWidget now uses TunableLabel for freqLabel, handling tuneDeltaRequested signals to update frequency interactively. UI and project files updated to register and use the new component.

A try at #855

Thanks. I also tried something similar but with already existing FreqQSpingBox. I tested your solution but it is behaving somewhat unpredictable to me. Maybe it’s my mouse but when I rotate the wheel the frequency changes -+ 0.6 kHz. When I use Ctrl or Shift, it changes by 3 kHz, and with Ctrl+Shift it changes by 15 kHz.

Is it possible that this is caused by my mouse, or what was the intended behavior? For my mouse, the pixel and angle variables in wheelEvent are QPoint(0, 120) or QPoint(0, -120).

Also, some of the comments in effectiveStepHz do not match the code. The multipliers are 5, 25, and 125.

I was working on this with my laptop/trackpad and it was acting different than with my mouse. Sorry should have tested it there. I see on my mouse it takes a bit before it changes. I had the multipliers to try and follow what was in that request 1 then 500 then 2500. I'll spend some more time on it tonight.

Michael, no problem. I'm using a very cheap HP mouse, so it's possible that it makes larger/smaller steps. I haven't tested the trackpad.

Your patch works more consistently than mine. had to make one change. I know HamLib wants the frequency in Hz. I can cancel this PR since you already had a good solution.

Rig::instance()->setFrequency(ui->freqLabel->value()*1000000);
