task digitalobject:regen-derivatives is unusably slow on AtoM sites with thousands of digital objects

Running this task on a site with 150k digital objects+ is too slow to be realistically invoked. I believe this is due to the ORM and letting the task use raw SQL will speed it up exponentially (main slowdown is in updating nested set after inserting new derivatives).
