Better structEntry field options and example

[VisenDev]

Demonstrated advanced structEntry configuration with FieldOptions

            const color_field_options = .{ .fields = .{
                .r = .{ .min = 0, .max = 255, .widget_type = .slider },
                .g = .{ .min = 0, .max = 255, .widget_type = .slider },
                .b = .{ .min = 0, .max = 255, .widget_type = .slider },
                .a = .{ .disabled = true },
            } };

            try dvui.structEntryExAlloc(@src(), "dvui.Theme", dvui.Theme, dvui.themeGet(), .{ .fields = .{
                .dark = .{ .widget_type = .toggle },
                .style_err = .{ .disabled = true },
                .style_accent = .{ .disabled = true },

TODO

• [x] Add label_override: ?[]const u8 = null field to all FieldOptions
• [x] Add use_expander: bool = true field to StructFieldOptions(T)

@david-vanderson I'm ready for this to be merged if you approve.

Looks great - thanks!

Instead of the sliders, you could use sliderEntry() - you probably already tried it, but just in case.
