Plot rendering adds zooming functionality

Sometimes, Plot drawing requires a more detailed observation of curve fluctuations. Having a zoom function would be very convenient.

Hi! Qt 6.9.0 recently introduced built-in support for zooming and panning in 2D charts, and I’ve just added an initial implementation into Serial Studio.

Right now, it supports zooming with the mouse wheel and rectangle selection. It still needs a bit of fine-tuning to make it feel smoother and more intuitive, I will refine it in the coming days. This feature is planned for release in Serial Studio 3.0.7.

Below a screen recording showing it in action:

If you want, you can try this feature using the continuous build.

More changes:

• A crosshair overlay is shown over the plots with with current X/Y values
• Ability to zoom and navigate a plot in a similar way to how you would use a CAD program.

Below a screen recording to show how it works. You can try the latest continuous build to test the feature.

Please let me know what you think about it!
