Function default

default(node, key, childrenName?, keyName?, isAddCurrentKey?): string[]
Find the key of all the parent nodes of the target node

Example
```
import { findParentKeysByKey } from "tree-handle-lib";
const tree = [
   {
     key: 'a',
     children: [
       { key: 'b' },
       { key: 'c', children: [{ key: 'd' }] },
     ],
   },
   { key: 'e' },
   { key: 'f', children: [{ key: 'g' }] },
 ];
const _result = findParentKeysByKey(tree, 'd')
// ["a","c"]
```
Parameters
- node: TNode
  
  the root node of the tree，can be a single node or an array of nodes
- key: string
  
  the key of find the destination node
- childrenName: string = CHILDREN_NAME
  
  the child key name of the child node in the tree structure,default value is CHILDREN_NAME='children'
- keyName: string = KEY_NAME
  
  the key name of the node in the tree structure，default value is KEY_NAME='key'
- isAddCurrentKey: boolean = false
  
  append the current key after the return result key list
Returns string[]
