Bug fixes

v3.6.0.0

v3.6.0.0

New features

1. add counter for sum_i value_i * weight_i for Ostap::WStatEntity - From now it allows the correct evaluation of uncertainty for
   the weighted sums (many thanks to @DmitryYuGolubkov Dima Golubkov)
2. add Ostap::EffEntity as C++ version of ostap.stats.counters.EffCounter with binomial efficiency & binomial interval estimations

Backward incompatible

1. From now the constructor for Ostap::WStatEntity object requires the third counter (for value_i * weight_i ).
   The old counters could not be deserialized now!

Bug fixes

v3.5.5.0
