Upload API Extensions

The upload API is very limited currently. For context, I'm working on importing a large number of images from an existing system and having to basically just push them all into 1 folder as there is no means to dynamically create folders to help organize the images. It is also impossible to know if I've previously uploaded an image as there is no ability to lookup existing images currently in the Asset Library. So in a nutshell, I would be looking to see a full set of CRUD operations for files which should support both ID and filename based matching. Additionally it would be nice to have CRUD operations for folders as well.
