        • Backward incompatible "GOST3410Curve" initialization: all
          parameters are passed not as big-endian encoded binaries, but
          as integers
        • Backward incompatible change: "gost3410.CURVE_PARAMS" is
          disappeared.  "gost3410.CURVES" dictionary holds already
          initialized "GOST3410Curve".  Just use
          "CURVES["id-tc26-gost-3410-12-512-paramSetA"]" instead of
          "GOST3410Curve(*CURVE_PARAMS["id-tc26-gost-3410-12-512-paramSetA"])"

*3.12*
        • Added mode argument to "pygost.gost3410_vko.kek_34102012256",
          because 256-bit private keys can be used with that algorithm
          too.
        • Fix incorrect degree sanitizing in
          "pygost.gost3410.GOST3410Curve.exp" preventing using of
          "UKM=1" in "pygost.gost3410_vko.kek_*" functions.

        • "gost3410.prv_unmarshal", "gost3410.pub_marshal",
          "gost3410.pub_unmarshal" helpers added, removing the need of
          "x509" module at all
        • "gost3410.verify" requires "(pubX, pubY)" tuple, instead of
          two separate "pubX", "pubY" arguments
        • 34.11-94 based PBKDF2 function added
