[In Progress] refactoring and debugging imagepipeline

poorly defined: how to accurately track if an image is color or not? This is causing a bug in the @with_frame decorator in GameModel.

There's also an antipattern of "cvimage.image = cvimage.mod_function()", to perform in-place modifications to images. This is the place for an ImagePipeline object.
