Add CALOFUTURE sequence to MiniBrunel

The CALOFUTURE sequence is added to the reco sequence. And FutureEcalCovar to the list of TopAlgorithms. This triggers FutureEcalZSup, EcalCaloFutureDigitFilterAlg, FutureEcalClust, FutureEcalShare and FutureEcalCovar to run. I've checked the minibrunel.hive-multi-thread nightly test runs fine* with this and that the number of clusters is the same as when running the same options with Brunel.

*The nightly test fails due to differences with the ref, all coming from the inclusion of the calo sequence, so this is expected and refs would need to be updated.
