Merge the images package into the convert package

The images package held low-level image primitives that existed only to be
consumed by convert (which already wrapped them), uploads, and handlers.
Folding them into convert removes a redundant package boundary and the thin
wrapper indirection, putting all image/media conversion code in one place.
