CLI utility to bulk import custom emojis for Mattermost v4.

--teamId - Team ID, not to be confused with the team name. The easiest way I've found to get this is to pop open the Network in the Developer tab and grab it from the URL
--loginId - The username or e-mail linked to the Mattermost account.
--password - Password for the Mattermost account.
--url - Mattermost Server URL. Example: https://mattermost.mymattermostdomain.com
