NepaliCalendarSystemToggleView
fun NepaliCalendarSystemToggleView(context: Context, initialCalendarSystem: CalendarSystem = CalendarSystem.BIKRAM_SAMBAT, language: NepaliDatePickerLang = NepaliDatePickerLang.ENGLISH, onHeightChange: (Float) -> Unit = {}, onCalendarSystemChange: (CalendarSystem) -> Unit): View(source)
The Bikram Sambat and Gregorian toggle as a plain View. Mirrors the iOS NepaliCalendarSystemToggleViewController.
The toggle owns its selection: it flips on tap and reports each change through onCalendarSystemChange.
