Feat: chokidar options

[jipodine]

Expose Chokidar options.

Let's not expose chokidar so we can change the underlying lib

Decoupling is fine.

However, we should find a way to get the initial events (creation of files and directories). The executeListener option of the onUpdate method only provides the initial tree, similar to calling getTree. (events is null.)

In Chokidar, the ignoreInitial option of the watcher provides both the initial tree and the creation events. It will affect any onUpdate registrations.

Let's create a list of add events with current tree if executeListener is set to true, something like:

onUpdate(callback, executeListener = false) {
      if (executeListener === true) {
         const values = this._treeState.getValues();
         values.events = createListOfAddEvent(values.tree);
         callback(values, {});
      }
      return this._treeState.onUpdate(callback, false);
}

Both on server and client side
