Adds the Wiener Filter method for energy reconstruction in the Tile Calorimeter

Guilherme Inacio Goncalves requested to merge ginaciog/athena:wiener-filter-offline-21 into 21.0

Implements the Wiener Filter method for energy reconstruction in the Tile Calorimeter, using two different approaches: Wiener Optimal (with seven sets of weights, optimized for the first three, the middle and the last three BCIDs in the train) and Wiener General (one set of weights for all BCIDs). The right approach is automatically selected whether the BCID information is available or not (through the TrigBunchCrossingTool).

Currently, weights are written directly to the source code, but storage using the COOL database is being implemented.

The filter can be used for both EBA and EBC E3 and E4 cells. Also, the current set of weights was designed for RUN 2 reconstructions, where mean luminosity is around <mu> = 40.
