Add `DataColumn` API for breaks in `Legend`/`Axis`

[AndreiKingsley]

Add new breaks (an analogue for all existing function) with DatColumn argument for passing breaks for axis and legend:

fun breaks(breaks: DataColumn<DomainType>, format: String? = null)

A common case:

legends {
   breaks(column.distinct())
}
