  mypy doesn't pick up type hints[BUG]
  <!--
  Thanks for reporting issues of python-telegram-bot!
  
  Use this template to notify us if you found a bug.
  
  To make it easier for us to help you please enter detailed information below.
  
  Please note, we only support the latest version of python-telegram-bot and
  master branch. Please make sure to upgrade & recreate the issue on the latest
  version prior to opening an issue.
  -->
  ### Steps to reproduce
  1. import python-telegram-bot modules into your `test.py` file (e.g. `from telegram import InlineKeyboardMarkup`)
  
  2. run `mypy test.py`
  
  3. receive the following output `error: Skipping analyzing 'telegram': found module but no type hints or library stubs`
  
  ### Expected behaviour
  mypy should pickup the typehints as they've been added in the latest release (version `13` )
  
  ### Actual behaviour
  mypy doesn't pickup the typehints.
  
  I'm confident this can be solved by either
  
  1. adding `python-telegram-bot` to `typeshed` 
  2. adding a `py.typed` file
