INFO: Output template options - show game number in filename

[macray76]

It may already be in there already but what do I need to add to the output template in config.yaml file to add the game number in the downloaded file for mlb and nhl games.

e.g. template: "{provider_id}.{start_date_time}.{away_team.abbreviation}@{home_team.abbreviation}.{GAMENUMBER}.{ext}"
