Support logo overrides per show instance

Is your feature request related to a problem?

I like the idea to have an image/logo associated with a recurring show, but it would be nice if it could be possible to upload specific images for different instances of the same show.

Describe the solution you'd like

The ideal solution would be a logo field when editing a show instance.
