support 'hier' in natural queries

bots can request the user's location, but this might make a conversation handler necessary?

>>> location_keyboard = telegram.KeyboardButton(text="send_location", request_location=True)
>>> contact_keyboard = telegram.KeyboardButton(text="send_contact", request_contact=True)
>>> custom_keyboard = [[ location_keyboard, contact_keyboard ]]
>>> reply_markup = telegram.ReplyKeyboardMarkup(custom_keyboard)
>>> bot.send_message(chat_id=chat_id, 
...                  text="Would you mind sharing your location and contact with me?", 
...                  reply_markup=reply_markup)
