Internal module to handle json fields, mainly helps to create modules with defined list selector match on compile

add to the module the use and use the macro list_selector/1 to specify the multiple selector and list_size/1 to specify the amount of elements to take

defmodule Some.Module do
  use ExCrawlzy.Client.Handlers.List

  list_size(5)
  list_selector("div.element-1/3")
  ...

and adds the functions list_size/0 and get_list_selector_selector/0 to the module

> Some.Module.list_size()
5
> Some.Module.get_list_selector_selector()
"div.element-1/3"
