Use Read/WriteDecorHandle to get data-dependency btw LArTimeVetoAlg and LArFebMonAlg right
The LArFebMonAlg(and other monitoring algs) rely on the LAr-Error word in the EventInfo object to ignore events polluted by noise-bursts. With this change, we make sure the LArTimeVetoAlg (that fills this word) is run before the LArFebMonAlg.
More Monitoring algs need to be updated like this one ...
