I added calendar endpoints to Starr library for two apps, but two more need them. Lots of copy/pasta. I left a branch half baked in the Starr repo. @bakerboy448 want to learn go?

Finally finished up that PR. Time to add calendar usage to notifiarr....

Finally looked into this. We already use history to get recent. We pull the entire starr content list to find upcoming. But we also use that list to create counters for what's on disk and how big it all is. Sonarr could be optimized since it loops series and pulls more data. But this doesn't seem like a problem that really needs fixing. The code only runs every hour or more.
