Remove ` - Single` & ` - EP` from release names automagically

[UnviableFriend]

Some services add these bits to the ends of release titles. Currently atisket automatically removes them from the titles.

Agreed that this should be removed, ideally in combination with setting the release group type instead. We just have to be careful not to change release titles legitimately ending in EP.
Do you know any services other than Apple Music / iTunes which are doing this?

From a quick search it looks like it's probably just Apple adding it after all

I'll do this as part of #15
