Fix the Tau second stage Roi sizes

The second stage tau Roi is intended to be wider than the first stage Tau Roi, this adds configurable parameters to allow the second stage Roi size to be adjusted.

At present, the second stage tau Roi takes it eta and phi widths from the first stage Roi, but tightens the Roi in z at the beamline, and is thus a strict subset of the first stage Roi meaning the second stage tracking would not be needed at all. This increases the Roi eta-phi width for the second stage taus.

As a result of increasing the second stage Roi width, the tau counts will likely change. These will be updated once the CI tests have executed.
