In our AOS weekly meeting last week, it was decided that the flags in the `combineZernikes` metadata should be integers not floats. Also, the butler storage for the CWFS Zernikes needs to be modified since the way the `EstimateZernikesTask` currently works only the metadata for the final pair of CWFS detectors is stored in the butler. The subtask needs to be modified so that all pairs of detectors will have metadata stored in the butler.
