A trait for performing operations on Secp2561 curve points.
Provides operations needed for elliptic curve cryptography, including point addition
and scalar multiplication.

Trait functions
get_coordinates
Returns the x and y coordinates of the curve point.

self: Secp256Point, other: Secp256Point,
) -> Result>
mul
Performs scalar multiplication of a curve point.
Multiplies self by the given scalar value.
Signature
