rototiller: introduce module.finish_frame()
Add a hook for post-render serialized frame completion, some of the renderers may have state to cleanup after rendering a frame. A future commit may change add a return value to control flow for features like multi-pass rendering within a given module. The raytracer for example may want to add concurrently executed post filters, and having a non-void return from finish_frame() would be a tidy way to tell rototiller "go back to prepare->render for this context" as many times as necessary, keeping the pass state in the context. For now its return is void however, as I just need a cleanup hook as the raytracer becomes more stateful per frame with a BIH spatial index in the works.
