TSN is a bunch of Canadian all-sports TV channels, similar to American
ESPN.

TSN schedule data comes from the web: https://www.tsn.ca/live/schedule

Upon inspection of its programs, that website seems to pull the
schedule from urls like this:

https://capi.9c9media.com/destinations/tsn_web/platforms/desktop/channelAffiliates/tsn1/schedules?starttime=2023-11-22T16:21:58-0800&endtime=2023-11-29T16:21:58-0800

And so my program reads from those, and puts it out here in text
files once per day.
