find optimal parameter for `wait_for_video(min_wait, max_wait)` option

[harupong]

currently they are set to (60, 600)

min_wait is used when the livestream is not scheduled

So the current setup sends a request to YouTube every 60 seconds, which seems a little too much. I think we can reduce the frequency to 10 minutes.

max_wait is used when the livestream is scheduled

This is used when the livestream is scheduled. So if the livestream is scheduled for 10:00, and it's 9:00 now, ytpodgen will send a request to YouTube every 10 minutes. This is to avoid sending too many requests to YouTube.

I think by setting this to so long, like 1 day(86,400sec), we can both

• reduce the frequency of requests to YouTube
• if the livestream is scheduled within 1 day, ytpodgen will wait for the livestream to start till the scheduled time.
