TV listings. Free keys: 1 per call.
eventstv.php?c=: a channel by name (e.g. "TSN 1").
eventstv.php?id=: by channel id (TvListing.channelId), not event id.
eventstv.php?d=: listings for a day, optionally a sport, or a country and sport. The API returns an empty body for a country without a sport, so that is rejected here.
