test impl

[dragan2234]

Currently, it's giving an InvalidPoint error on f1f2. I took f1f2 parameters from arkworks impl. I also noticed that we've only put a base field and generator when defining the curve. Not sure if/how should we also add other things like:

//! * Scalar field: r =
//!   13108968793781547619861935127046491459309155893440570251786403306729687672801
//! * Valuation(q - 1, 2) = 32
//! * Valuation(r - 1, 2) = 5
//! * Curve equation: ax^2 + y^2 =1 + dx^2y^2, where
//!    * a = -5
//!    * d = 45022363124591815672509500913686876175488063829319466900776701791074614335719

Or the actual curve equation with parameters a and d is added just in ShortWeierstrass form(with a and b)?

But then seems we are still missing scalar field.

Also, I think parameters for new_base should be in hex format instead of dec.

ShortWeierstrass form is:
y^2 = x^3 + a * x + b

...will continue tomorrow

For the curve form, I took the values from arkwork here https://github.com/arkworks-rs/curves/blob/master/ed_on_bls12_381_bandersnatch/src/curves/mod.rs
