title: send video through telegram python api
body: <p>I want to send a video through the API, there are functions to send text, images, audio and documents. Is there a function to send videos or should I use this function to do so?</p>
  
  <p>bot.send_document(chat_id=chat_id, document=open('tests/test.zip', 'rb'))</p>
  
  <p>Is there an easier/more correct way?</p>
