animate-slidedown fails when a Tailwind prefix is used

[cagataycivici]

Add hiddenClass option to define the class name that hides the element, also the class to add/remove should default to;

 if (binding.value.enterActiveClass.includes('slidedown')) {
      target.style.height = '0px';
      removeClass(target, binding.value.hiddenClass || binding.value.enterFromClass);
      target.style.maxHeight = target.scrollHeight + 'px';
      addClass(target, binding.value.hiddenClass || binding.value.enterFromClass;
      target.style.height = '';
  }
