item_wrap for str and int

[jgroom33]

item_wrap=False currently only supports list of dict

It should also support list of str and int

Input:

{"my_str_items":["a","b"]}

item_wrap=False output:

<all>
  <my_str_items type="list">
    <item type="str">a</item>
    <item type="str">b</item>
  </my_str_items>
</all>

item_wrap=True output:

<all>
  <my_str_items>a</my_str_items>
  <my_str_items>b</my_str_items>
</all>
