suggestion: use the overwatch league schedule to launch the streams

[omarsaad98]

https://overwatchleague.com/en-us/schedule has a webcal url that can be parsed to find streaming times (sync calendar -> other)

I suggest this app use this API to find out when OWL is streaming instead of relying on TWO constantly running chromium instances, which has the disadvantage of consuming a surprising amount of memory and the app would only need to check the API on rare occasions instead of polling every 5 minutes like it does now.

I suggest this become an option when launching the app
