Use scientific notification for Labeled sliders values for big/small values

[Czaki]

In https://github.com/napari/napari/issues/6522 napari got information that for really small numbers the the labels are unreadable:

The author of Issue suggests that maybe replacing use of scientific notation for representing small values. It may be also useful for large numbers.

This may be not so trivial as it will require to re implement SliderLabel that may require to use QLabel as base class.

What did you think?

Cool! I really like this feature to be implemented. I believe implementing scientific notation in labels for double sliders would be highly beneficial, especially in scientific applications. This enhancement would improve usability and precision for users who work with large or small numerical values. Thank you.
