configure inclusivity on isBetween

https://momentjs.com/docs/#/query/is-between/

Actual state:

dayjs('2010-10-20').isBetween('2010-10-20', dayjs('2010-10-20'));   // false
dayjs('2010-10-20').isBetween('2010-10-19', dayjs('2010-10-20'));   // false
dayjs('2010-10-20').isBetween('2010-10-19', dayjs('2010-10-21'));   // true

We must be able to enable inclusivity by passing a string (like in moment):

moment('2016-10-30').isBetween('2016-10-30', '2016-12-30', null, '()'); //false
moment('2016-10-30').isBetween('2016-10-30', '2016-12-30', null, '[)'); //true
moment('2016-10-30').isBetween('2016-01-01', '2016-10-30', null, '()'); //false
moment('2016-10-30').isBetween('2016-01-01', '2016-10-30', null, '(]'); //true
moment('2016-10-30').isBetween('2016-10-30', '2016-10-30', null, '[]'); //true

Exemple of function:

function _isBetween (date, dateStart, dateEnd, includeStart = false, includeEnd = false) {
  let result = date.isAfter(dateStart) && date.isBefore(dateEnd);
  if (!result && includeStart) result = date.isSame(dateStart);
  if (!result && includeEnd) result = date.isSame(dateEnd);
  return result;
}
