Use wgt=0.5 for r/z when requested
Add option to use hardcoded extrapWeight=0.5 for r and z when constructing a hit (in simulate_hit()) in TFCSPredictExtrapWeights.
Also, force extrapolation weights to be within [0,1] (this is a protection, current networks do not always satisfy this but future ones will satisfy this by construction).
@mfauccig can we merge this?
