Feature/add forms: Add friendless towards query/formdata.

[Bishwas-py]

• Multiple query string key can be passed; localhost/?isawesome=1&isawesome=2 will be {'isawesome': [1,2]}
• Multiple formdata can be passed

  
  class Data(Form):
  plain_text: list[str] # or str both work awesomely fine

@djapify(allowed_method=['GET', 'POST']) @csrf_exempt def test_proxer_form_view(request, data: Data) -> str: return str(data.plain_text)

this can only be accepted from a post request.

- `SourceAble` is renamed to `Outsource`, and `_context`, `_validation_info` and `_source_obj` are renamed to `_ctx`, `_info` and `_obj` respectively. For the sake of simple-looking short code.
- `ImageUrl` and `QueryList` added
