New option - delete files from radarr/sonarr

[aviadlevy]

First of all, thanks for you script. this is very needed.
This script lacks a specific feature that improve my "media management" significantly - to delete the files after I finished watched them.

I implement it for my own use case and decided to share it with you.

This is obviously a risky feature since it will delete files and you need to make sure that this is something you actually wanted to do

I tested it on my own environment and it works perfectly.
