Interval limit

[didoda]

This introduces an :interval-limit option to limit the number of hours intervals per day.
Often opening hours are meant to be 2 intervals (morning and afternoon hours), so default :interval-limit is 2.

Usage:

<business-hours
    :days="holidays"
    name="holidayHours"
    type="select"
    :time-increment="60"
    :interval-limit="2"
    color="#00af0b"
  ></business-hours>

@sbarry50 do you think this makes sense? would you do that in another way?
