[Feature] Prowlarr Support

[bycytov]

Would be nice to use instead of Jackett. My experience this is much better

wow, I had no idea there was a popular competitor to jackett, and it supports usenet. I'll have to test drive this at some point to fully understand it. Thanks for sharing.

I'm closing this because I don't plan on extending support beyond jackett unless jackett closes it's doors.
