Proper integration of energy redistribution #13

If implemented in an aov shader, I need a way to discard the re-distributed samples from the main image.
Find a workaround for not being able to write to other buckets. It would be relatively OK to write all of the redistributed samples after each bucket, so not all buckets need to be accessed all the time.

Potentially could write out the to-discard samples to an extra aov and difference them afterwards. Not an amazing workflow, but could work for now
