[Enhancement] Generic SegmentedControl

[mikkel-ol]

• [x] I have written a good issue

Describe the enhancement

SegmentedControl should be generic to allow narrow types to be passed to items and value while being passed back to segmentSelect()

Describe the solution you'd like

Let component SegmentedControl be generic but extend existing and required type SegmentItem and use the generic for items and output segmentSelect

Have you considered any alternatives?

No

Are there any additional context?

No
