Download file using WebClient

Right now, the only way to download a file from Slack is to do something like this:

import requests
response = requests.get(url_private, headers={"Authorization": f"Bearer {TOKEN}"}, timeout=30)

However, this does not respects the parameters passed to WebClient. We should be able to do something like:

client = WebClient()
response = client.get(url_private)

Or something along those lines.
