Feature request. Add return to a specific fragment.

[zakrodionov]

It would be convenient if there was navigation in a certain fragment.
For example, we have a chain a -> b -> c -> d -> e->, and I would like to return,for example, from e to b.

override fun backToFragment(fragment: Class<out Fragment>, refresh: Boolean) {
       val lastCurrentStackIndex = fragNavController.currentStack?.lastIndex ?: 0
       val indexOfFragment =
           fragNavController.currentStack?.indexOfLast { it.javaClass == fragment } ?: -1

       if (indexOfFragment == -1) {
           fragNavController.clearStack()
           fragNavController.pushFragment(fragment.newInstance())
       } else {
           fragNavController.popFragments(lastCurrentStackIndex - indexOfFragment)
       }

       if (refresh) {
           (fragNavController.currentFrag as? BaseFragment)?.refresh()
       }
   }
