Currently the keyword for setting the output DAOD formats in the new CA-based derivation framework transform
requiredDerivedFormats. We have agreed that this is too long and since the keyword
formats is available, we've decided to switch to this. Consequently once this MR is merged the new transform would be used as follows:
Derivation_tf.py --CA --inputAODFile aod.pool.root --outputDAODFile daod.pool.root --formats PHYS PHYSLITE ETC
Since this new transform isn't used in production yet, this MR will have no impact on any existing production or activities.
