docs: Returns the range as a set of minutes. A value of {@literal false} means 'closed' and a value of {@literal true} means 'open'. It is
  only allowed to call this method if the hour range represents only one day. This means a value like '18:00-03:00' will lead to an
  error. To avoid this, call the {@link #normalize()} function before this one and pass the result per day as an argument to this
  method.
  
  @return Bitset representing the minutes of a day (0 = 00:00 - 1439 = 23:59).
