A_gamma and gamma_A variables

[heswithme]

In init function of twocrypto we have lines:

    self.initial_A_gamma = packed_gamma_A 
    self.future_A_gamma = packed_gamma_A

which puts packed variables (packed by factory in order [gamma, A]) into single variable, that DOES NOT preserve the packing order in it's name.
While fix is simply renaming a variable, this one is public and might be used by some integrators. We need to check before proceeding with fix.
